WebHeat is added slowly until the gas temperature is uniformly 600 K, after which the gas volume is 4 m 3 and the piston is 2 m above its initial position. If the piston motion is sufficiently slow, the gas pressure at each instant will have practically the same value ( psys = 1 atm) throughout. WebOct 7, 2024 · Isothermal Process A thermodynamic process in which the system’s temperature remains constant is known as an isothermal process. Heat transfer into and out of the system must typically occur at such a slow rate in order for the reservoir temperature to be constantly adjusted through heat exchange.

WebOne condition, known as an isothermal expansion, involves keeping the gas at a constant temperature. As the gas does work against the restraining force of the piston, it must absorb heat in order to conserve energy. Otherwise, it would cool as it expands (or conversely heat as it is compressed).
