Reversible Isothermal and Adiabatic process

Reversible Isothermal and Adiabatic process

Work is the mose of transfrence of energy. If the system involves gaseous substance and there is difference of pressure between system and surroundings, such a work is referred to as pressure - volume work (W_(PV)= -P_(ext)DeltaV) . It has been observed that reversible work done by the system is the maximum obtainable work. w_(rev) gt w_(ir r) The works of isothermal and adiabatic processes are different from each other. for isothermal reversible proces, W_("isothermal reversible")=2.303 nRT log_(10) (V_(2)/V_(1)) W_("adiabatic reversible")=C_(V) (T_(1)-T_(2)) A thermodynamic system goes in acyclic process as represented in the following P-V diagram: 1. For an ideal gas, consider only P-V work in going from an initial state The net work done during the complete cycle is given by the area:
