In the previous two programmes we have developed the ideas of work, heat and energy. We have also seen how the energy of a system changes with work and heat interactions at the boundary. So far in the problems you have met, the state of a system has been completely specified; this means all properties have been given. In this programme you will learn how to calculate, or look up in tables or charts, those properties which need to be found. This may be done from formulae or from tables of data acquired and refined over many years. It will enable you to tackle a much wider range of problems on systems and the First Law, which will follow in Programme 5.
