If \( \Delta U \) and \( \Delta W \) represent the increase in internal energy and work done by the system respectively in
\( \mathrm{P} \) a thermodynamical process, which of the following

WV is true?
(a) \( \Delta U=-\Delta W \), in an adiabatic process
(b) \( \Delta U=\Delta W \), in an isothermal process
(c) \( \Delta U=\Delta W \), in an adiabatic process
(d) \( \Delta U=-\Delta W \), in an isothermal process
