Isothermal process

An isothermal process is a chynge o a seestem, in which the temperatur remains constant: ΔT = 0. This teepically occurs when a seestem is in contact wi an ootside thermal reservoir (heat bath), an the chynge occurs slawly eneuch tae allae the seestem tae continually adjuist tae the temperatur o the reservoir throu heat exchynge.
