Chapter 9: First Law of Thermodynamics


Specific heat capacity
Specific latent heat
Internal energy
First law of thermodynamics



(a) Define and use the concepts of specific heat capacity and specific latent heat.

(b) Show an understanding that internal energy is determined by the state of the system and that it can be expressed as the sum of a random distribution of kinetic and potential energies associated with the molecules of a system.

(c) Relate a rise in temperature of a body to an increase in its internal energy.

(d) Recall and use the first law of thermodynamics expressed in terms of the increase in internal energy, the heat supplied to the system and the work done on the system.
