For instance, both human engines and heat engines extract heat energy at a higher temperature, do work, and then transfer waste heat energy to lower temperature surroundings. which is equal to the mechanical work done on the mass. Make sure you completed the entire lab and answered all parts. 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.
