Q
Specific latent heat of fusion
A
The energy required per unit mass of a substance to change it from a solid to a liquid without a change in temperature
3
Q
Specific latent heat of vaporisation
A
The energy required to change unit mass of a substance from liquid to gas without a change in temperature.
4
Q
internal energy
A
Sum of random distribution of kinetic and potential energies in a system
5
Q
First law of thermodynamics
A
The increase in internal energy of a system is equal to the heat supplied to the system and the work done on the system
