The molar heat capacity of an ideal gas is $C_{P,m}=25.0+0.0200T\mathrm{J}\mathrm{mo}{\mathrm{l}}^{-1}{\mathrm{K}}^{-1}$ ($T$ in K). With $R=8.314\mathrm{J}\mathrm{mo}{\mathrm{l}}^{-1}{\mathrm{K}}^{-1}$, the change in internal energy when one mole is heated from $300\mathrm{K}$ to $500\mathrm{K}$ is

1. A$6600\mathrm{J}$
2. B$5000\mathrm{J}$
3. C$2443\mathrm{J}$
4. D$4937\mathrm{J}$
