Why is it that if I fill my ice trays with cold water the ice is difficult to get out, but if I fill them with hot water the ice comes out much easier?Water heated in a hot water heater is not suitable to ingest.Don’t use it for drinking, cooking, preparing baby formula, or making ice.It is okay to use for bathing, showering, laundry, washing dishes, and cleaning.The reason that water from the hot water tank is not good to ingest is that it has too many dissolved heavy minerals in it — including lead and many other heavy metals that we should not be swallowing.Fresh water coming in to the house from the water mains in the street has only trace amounts of these metals at first.But they build up in the water tank when the water sits in the tank for long.The metals form scale on the inside of the tank.Then fresh water sits heated in the tank, dissolving the heavy metals to an unacceptable level.When you draw the hot water, it contains more heavy metals than you realize.Boiling the water does not reduce the heavy metal contamination.(1) Don’t use tap water hot from the tank for drinking, making coffee or tea, baby formula, cooking, or making ice — or for any other purpose that gets it inside your body.(2) Start with fresh water that you let run until it is cold — straight from the mains. Don’t ingest even cold water that has been sitting in your indoor pipes until it is lukewarm. (3) Let the cold water run until it is “outdoor” cold and then heat it.(4) To avoid wasting water, let it run until it is outdoor cold, then fill a large pitcher with the cold water. Then use this instead of having to run water for every drink or cup of tea.(5) It is metals and other contaminants you are avoiding, not germs. Boiling the water will not get rid of the metals.(6) Hot tap water straight from the hot water tank is safe to use for washing, bathing, showering, dish washing, laundry, and cleaning. (7) All these uses for hot tap water are safe for the baby too.It’s just not safe for the baby to swallow in any form.(8) Ditto for your pets and fish tank. You can use hot tap water to wash your pets’ dishes and bowls, to bathe them, and to clean the fish tank. But use fresh, lead-free water for them to drink and to fill the fish tank.————————Here is a short article from The New York Times about drinking hot tap water:Lead Contamination - Tap Water - Medicine and Health

There are some very well thought out and science-based answers to this question, so it is with some hesitation that I submit my response. Many of the other answers rightly point out that the process of creating ice is energy intensive, and could itself contribute to further waste heat, greenhouse gases & carbon emissions- the very problem we are trying to remedy. However, there MAY be a way around this; for years I’ve had an idea of semi-autonomous barges moored next to those glaciers & ice shelves that adjoin the polar seas. If these barges had a large array of very efficient tracking photovoltaic panels that charged a battery bank (similar to Tesla’s NanoWall), you would have a non-polluting source of power (other than their production and transport). Instead of using inefficient conventional ice makers, if you used snow-makers that can be seen at almost any ski resort, you could utilize the low ambient temperatures of these areas to your advantage; by pumping water through the snow makers when the temperature is close to, or below freezing (at night, for example), you are now creating snow, the raw material of glaciers… And with no contribution of waste heat or carbon emissions. Obviously, it would be better if the sea water could be filtered and desalinated first, as fresh water has a higher freezing point than salt water, would create better snow/ice (longer lasting), and would extend the service life of the equipment greatly. Perhaps it would be possible to use reverse osmosis filtration to desalinate the seawater, again powered by the solar/battery bank system that would power the pumps for the snow makers if their energy consumption was low enough? Or perhaps solar distillation would be a more energy efficient method, but heat is usually a by-product of distillation. I read somewhere of running water through pipes in an insulating media (clay was mentioned) attached to the back of photovoltaic panels to increase the panel’s efficiency (it was represented that they work better if kept cool), and using the warmed water for domestic hot water, although that is not applicable here, it could make a heat pump (if needed/applicable for the equipment or for the process) or solar distillation more efficient by reducing the amount of degrees (and therefore the energy required) that the water would need to be heated in the desalinization process. Some cooling systems make use of brine as a chilling medium, and the desalinization process would certainly be able to provide that. As per their use at ski resorts, long sections of hoses could transport the water from the pumps to the snow makers, allowing some flexibility in their placement so as to have greater impact- slightly behind the active face of the glacier or ice shelf, or with enough hoses/piping, further behind the active face. I have thought, however, that the active, calving face of a glacier (the “foot”) where it meets the sea is not the best place to locate all this equipment (mooring a barge beneath the face of a calving glacier or ice sheet that can be hundreds of feet high both subjects it to possible damage, and shading of the solar array), and perhaps locating it on top of, or closer to the head of the glacier would be safer for the equipment, although more difficult… It would have to be protected from crevasses, fissures, and movement of the glacier. Rafting could be an answer, but would be far more expensive, labor/maintenance intensive, and installation of the equipment would also be much more difficult than simply towing a barge with all the equipment installed… However, for non-littoral glaciers (those located well inland), a comparable system could be reproduced, and in many ways simplified (no need for desalinization), access to power transmission lines, access for maintenance & repositioning of equipment could be easier than the idea of barges. To be honest, I don’t know if a few hundred, or even a few thousand of these barges would have any meaningful impact on the loss of glaciers and ice shelves… For the solar panels to work, they could only operate part of the year, when there is enough sunlight to generate electricity. During the respective polar winters, there would be months when there is simply no, or insufficient amounts of sunlight. Equations of how many of these stations, at an average output of “snow” each, based upon the capacity of the solar panels, the batteries, the pumps, and meteorological conditions may mean that it is simply not practical. I do feel, however, that if scaled up to a level (tens of thousands of units) where it had even a modest impact (turning millions of gallons of melt-water back into snow, and therefore into ice, helping to stem rising sea levels, as well as creating coverage for exposed areas of land, lowering its albedo, and therefore heat absorption) coupled with a serious global effort to curtail the emission of carbon/greenhouse gasses, re-forestation, and perhaps carbon capture & sequestration, that a worst-case scenario could be avoided. Putting the practical realities aside, the manufacturing of ice to replenish glaciers and ice sheets, thus slowing sea level rise and global warming is FAR from a bad idea! I would certainly welcome any feedback or scientific/mathematical input- could this idea even work?

Now that completely depends on which stream you want to pursue post your graduation. If you want to continue with engineering then I would recommend GRE that would be more beneficial and little less competitive. Else there are many more options like doing MBA or preparing for IAS or alike services. First one needs to streamline the area they want to peruse post grad in coz now after this changing streams is nearly impossible.

Amorphous ice (non-crystalline ("vitreous") ice) is an amorphous solid form of water. Common iceis a crystalline material where the molecules are regularly arranged ..

I was selected for a summer internship 2016.I tried to be very open while filling the preference form: I choose many products as my favorite products and I said I'm open about the team I want to join.I even was very open in the  location and start date to get host matching interviews (I negotiated the start date in the interview until both me and my host were happy.) You could ask your recruiter to review your form (there are very cool and could help you a lot since they have a bigger experience).Do a search on the potential team.Before the interviews,  try to find smart question that you are going to ask for the potential host (do a search on the team  to find nice and deep questions to impress your host). Prepare well your resume.You are very likely not going to get algorithm/data structure questions like in the first round. It's going to be just some friendly chat if you are lucky. If your potential team is working on something like machine learning, expect that  they are going to ask you questions about machine learning, courses related to machine learning you have and relevant experience (projects, internship). Of course you have to study that before the interview. Take as long time as you need if you feel rusty. It takes some time to get ready for the host matching (it's less than the technical interview)  but it's worth it of course.

DHS prepares a Form I-213, Record of Deportable/Inadmissible Alien, which sets forth information to support the respondent's alleged alienate and memorability from the United States. These two documents are essential to any case before a U.S. immigration court, as they are the starting point for removal proceedings.

Change of Address Notification Required. All foreign nationals, including legal permanent residents (green card holders) who are not U.S. citizens are required by Section 265 of the Immigration and Nationality Act to notify the USCIS of address changes while in the United States.

THE IMMIGRATION BOND MONEY. REFUNDED. When an immigration case has run its course and the alien has not violated the terms of the bond, ICE cancels the immigration bond. ... After the cancellation is processed, which can take a long while; the obliged receives a Form I-391 Notice — Immigration Bond Cancelled.

Deportation — — or more properly “removal” is the action by which the government removes an alien from the United States. ... A notice to appear is a form, I-831, and sets out the government's allegations as to the alien's status and reasons they are removable from the United States.

Surety bond\u2013 The detainee's friends or family can work with an immigration bond agent to get a surety bond. The agent will typically charge 15-20% of the total bond amount, and the money or collateral you furnish is non-refundable. ... The cash bond can be paid by cash, money order, Cashier's check, or U.S. bonds or notes.
