What is isothermal expansion |
|
Answer» An isothermal process is a change of a SYSTEM, in which the temperature remains constant: ΔT =0. ... In other words, in an isothermal process, the value ΔT = 0 and THEREFORE the change in internal energy ΔU = 0 (only for an IDEAL gas) but Q ≠ 0, while in an adiabatic process, ΔT ≠ 0 but Q = 0. |
