When \( 1 \mathrm{~mol} \) of gas is heated at constant volume temperature is raised from 298 to \( 308 \mathrm{~K} \). Heat
\( \mathrm{P} \) supplied to the gas is \( 500 \mathrm{~J} \). Then which statement is

W correct?
(a) \( q=w=500 \mathrm{~J}, \Delta E=0 \)
(b) \( q=\Delta E=500 \mathrm{~J}, w=0 \)
(c) \( q=w=500 \mathrm{~J}, \Delta E=0 \)
(d) \( \Delta E=0, q=w=-500 \mathrm{~J} \)
