Answer» Anisothermal processis achangeof asystem, in which thetemperatureremains constant: ΔT=0. This typically occurs when a system is in contact with an outside thermal reservoir (heat bath), and the change in the system will occur slowly enough to allow the system to continue to adjust to the temperature of the reservoir throughheatexchange. In contrast, anadiabatic processis where a system exchanges no heat with its surroundings (Q=0). In other words, in an isothermal process, the value ΔT=0 and therefore the change ininternal energyΔU=0 (only for an ideal gas) but Q≠0, while in an adiabatic process, ΔT≠0 but Q=0.
