Which one of the following equations does not correctly represent the first law of thermodynamics
\( \mathrm{P} \)
for the given processes involving an ideal gas?
W
(Assume non-expansion work is zero)
(1) Cyclic process: \( q=-W \)
(2) Adiabatic process: \( \Delta U=-W \)
(3) Isochoric process: \( \Delta \mathrm{U}=\mathrm{q} \)
(4) Isothermal process : \( q=-W \)
