The first law of thermodynamics extends the principle of conservation of energy to include heat as well as mechanical energy. The first law of thermodynamics extends the principle of conservation of momentum to include molecular collisions. The amount of heat added or removed from a thermodynamic system depends on the path taken on a pV diagram.
One important use for pV diagrams is in calculating work. The product pV has the units of Pa x m (N/m').m - N.m-J in fact, the absolute value of the work done by the gas (or on the gas) during any process equals the area under the graph corresponding to that process on the pV diagram of the gas increases in volume, it does positive work, if the volume decreases the gas does negative work (or ...
