Problem

A monatomic ideal gas completes the four-step cycle ABCDA described below: • AB: Volume held at

2.0\,\text{L}

while pressure increases from

100\,\text{kPa}

200\,\text{kPa}

. • BC: Pressure held at

200\,\text{kPa}

while volume expands to

5.0\,\text{L}

. • CD: Volume held at

5.0\,\text{L}

while pressure decreases back to

100\,\text{kPa}

. • DA: Pressure held at

100\,\text{kPa}

while volume compresses back to

2.0\,\text{L}

. What is the net work done on the gas after one complete cycle? (a)

+3.0\times10^{2}\,\text{J}

(b)

-6.0\times10^{2}\,\text{J}

(c)

-3.0\times10^{2}\,\text{J}

(d)

+6.0\times10^{2}\,\text{J}
