Problem

A sample of ideal gas initially at a pressure of

1.0\times10^{5}\,\text{Pa}

and a volume of

2.0\,\text{L}

expands at constant pressure to a final volume of

5.0\,\text{L}

. During the expansion,

600\,\text{J}

of energy is transferred to the gas by heating. What is the change in the internal energy of the gas,

\Delta U

? a)

+600\;\text{J}

+450\;\text{J}

+900\;\text{J}

+300\;\text{J}
