The total entropy of a closed system is always increasing. Since pressure and volume are inversely proportional to each other, as pressure increases, the volume decreases. In the experiment, where a heat engine apparatus would be used, hot and cold baths would be considered as the heat reservoirs and mechanical work would be inferred from the up and down motions of the piston.

Each part of the cycle is easily identifiable, and the actual efficiency as well as the maximum possible efficiency can be easily determined. It has two air tubes leading from the cylinder: one going to a pressure sensor (which is measured using the Lab Pro) and the other leading to an air reservoir (aluminum can) that we will immerse in water to change the temperature of the air in the system. The PASCO TD-8572 Heat Engine/Gas Law Apparatus is employed in this experiment. The computer has produced the plots shown below, Determine the enclosed area on your P-V diagram.
