SUMMARY
In an isothermal process involving an ideal gas, the heat added or removed is equal to the work done on or by the gas. This is established through the first law of thermodynamics, where the change in internal energy is zero for a system returning to its initial state. The relevant equations for calculating heat in isothermal conditions do not involve temperature changes, as they do in isochoric or isobaric processes. Instead, the relationship is defined by the work done, which can be calculated using the ideal gas law.
