Definition and Meaning of Melting and Boiling Points
Melting and boiling points are critical physical properties that indicate the temperature at which a substance transitions between solid and liquid states (melting point) and between liquid and gas states (boiling point). Understanding these points is essential for various applications in science and industry, including material selection, chemical processing, and environmental studies.
The melting point is defined as the temperature at which a solid becomes a liquid. For example, the melting point of ice is zero degrees Celsius (32 degrees Fahrenheit). Conversely, the boiling point is the temperature at which a liquid turns into vapor. For water, this occurs at one hundred degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure.
