WebMay 17, 2024 · An isothermal process is a thermodynamic process in which if you take to measure the temperature of the system at some time in the process and then measure it again, later in the process, the measurement of would be the same, independent of what two times you decided at whim to measure. Reversibility is a completely separate question. WebIsothermal : The process is at a constant temperature during that part of the cycle (T=constant, ). Energy transfer is considered as heat removed from or work done by the system. Isobaric : Pressure in that part of the cycle will remain constant. (P=constant, ).
