An isothermal process takes place at constant temperature.
During an isothermal expansion, the work done by an ideal gas
is W = nRT ln(Vf/Vi), where n the number of moles, R is the
universal gas constant, T is the absolute temperature, Vi is
the initial volume of the gas, and Vf is its final volume.
In an isothermal process, the internal energy of an ideal
gas does not change.
In an isobaric process, the pressure remains constant, and
W = P(Vf Vi).
In an isovolumetric process, V remains constant, and W =
In an adiabatic process, Q = 0, i.e., no heat is added to,
or removed from, the system.
