First, for the isothermal process, the work done is, While for an isobaric process, the work done is, then the total work done by the heat engine for one cycle of the Ericsson cycle is given as. 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 effect was observed as a rise in the object on the platform so is the piston height from state B to C. However, if the air chamber can is placed in the cold bath, the temperature and volume will decrease. 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.
