Key Concepts

Isothermal Process

An isothermal process is one in which the system’s temperature remains constant throughout. For an ideal gas, this implies that the internal energy does not change, because internal energy is solely a function of temperature. In the context of the problem, the relevant quantity that is zero is the change in temperature and, under ideal conditions, the change in internal energy.

Adiabatic Process

An adiabatic process is characterized by the absence of heat exchange between the system and its surroundings, meaning that the heat transfer (Q) is zero. This concept is fundamental when considering processes where the system is perfectly insulated, so any change in the internal energy is solely due to work done on or by the system.

Isochoric Process

An isochoric (or isovolumetric) process occurs at a constant volume. In such processes, since there is no change in volume, the work done by or on the system is zero because work in thermodynamics is typically associated with volume change (W = P?V).
