<P> An isothermal process is a change of a system , in which the temperature remains constant : ΔT = 0 . This typically occurs when a system is in contact with an outside thermal reservoir ( heat bath ) , and the change will occur slowly enough to allow the system to continue to adjust to the temperature of the reservoir through heat exchange . In contrast , an adiabatic process is where a system exchanges no heat with its surroundings ( Q = 0 ) . In other words , in an isothermal process , the value ΔT = 0 and therefore ΔU = 0 ( only for an ideal gas ) but Q ≠ 0 , while in an adiabatic process , ΔT ≠ 0 but Q = 0 . </P>
