The heat engine cycle is completed by immersing the can in cold water, which returns the air pressure and volume to the starting values. The total entropy of a closed system is always increasing. The computation for the values of thermodynamic work was shown in Appendices. . If the pressure is kept constant (isobaric), the temperature will be allowed to change. A large significant percent difference indicates that there are possible sources of error like gas leaks, assumption that the working substance is an ideal gas and inconsistent temperature and pressure.
