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.
So sry if they are two long
