When1 mol of a gas is heated at constant volume, temperature is raised

1.	When1 mol of a gas is heated at constant volume, temperature is raisedfrom298 Kto 308 K.Heat supplied to the gas is500J. Then which statement is correct?
Answer» `q=W=500J, DeltaU=0` `q= DeltaU=500J,W =0` `q=W = 500 J ,DeltaU=W=0` `DeltaU=0,q=W= - 500J` SOLUTION :At CONSTANT volume, `DeltaV=0`. Hence, `W=0` .Further `DeltaU = q+W` As `W=0, DeltaU = q= 500J`
