| - | An [[wp>Isothermal_process|isothermal process]] is one which occurs at a constant temperature. In order for such a process too occur there should be a [[wp>Heat_reservoir|heat reservoir]], a large body in thermal contact with the system which has a temperature that will not significantly change as heat is exchanged with it. We will consider a [[wp>Quasistatic_process|quasistatic process]], which means it occurs slowly enough that the system can be considered to be in equilibrium at any given time. | + | An [[wp>Isothermal_process|isothermal process]] is one which occurs at a constant temperature.
