When $1 \, \text{mol}$ of a gas is heated at constant volume,the temperature increases from $298 \, K$ to $308 \, K$. If the heat supplied to the gas is $500 \, J$,which of the following statements is correct?

  • A
    $q = w = 500 \, J, \Delta U = 0$
  • B
    $q = \Delta U = 500 \, J, w = 0$
  • C
    $q = w = 500 \, J, \Delta U = 0$
  • D
    $\Delta U = 0, q = w = -500 \, J$
