This process is known as an isothermal expansion - so named because the data were collected slowly enough that the temperature of the gas in the system remained constant. This actual efficiency is compared to the theoretical maximum efficiency. The heat engine consists of air inside a cylinder that expands when an attached can is immersed in hot water. The temperature, at the states where it should be the same, is not constant so is the pressure. @ H5
