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$\Delta U = 0, q = w = -500 \, J$
