In this section we revise the concepts of heat, work and internal energy. You should check that you remember the properties of an ideal gas, summarised without proof here. You should also check out the glossary for the meaning of terms like ``adiabatic'' and ``function of state'' which will be assumed.
The only new material in this section is the definition of work in systems other than hydrostatic. However if past years are anything to go by, it is unlikely you will remember much of it without revision.
