Problem

A sample of

1.5\,\text{mol}

of an ideal monatomic gas is warmed from

300\,\text{K}

450\,\text{K}

while confined to a rigid container. What is the change in the gas’s internal energy? a)

1.3\times10^{3}\,\text{J}

8.4\times10^{3}\,\text{J}

2.8\times10^{3}\,\text{J}

4.7\times10^{3}\,\text{J}
