Answer 2

I am sry cant give u the the uh...expression but here are all the definition

1.thermal capacity: Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature.

2. Water equivalent: The water equivalent of a substance is equal to the amount of water needed to absorb the same amount of heat as that substance does for one degree of increase in temperature.

3. Evaporation: Evaporation is the process by which water changes from a liquid to a gas or vapor.


4. Boiling: Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
