Problem

An ideal gas at 400\,K is compressed isothermally from a pressure of

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

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

. Its initial volume is

0.020\,\text{m}^3

. What is the work done on the gas (nearest value)? a)

-2.8 \times 10^{3}\,\text{J}

1.4 \times 10^{3}\,\text{J}

2.8 \times 10^{3}\,\text{J}

3.8 \times 10^{3}\,\text{J}
