When 1 mol gas is heated at constant volume temperature is raised from 298 to 308 K. Heat supplied to the gas is 500 J. Then which statement is correct : -

Question

( A ) q = w = 500 J, $\Delta$U = 0
( B ) q = w = 500 J, $\Delta$ U = 0
( C ) $\Delta$ U = 0, q = w = – 500 J
( D ) q = $\Delta$E = 500J, w = 0
