1.2\,\text{atm}

, a volume of

3.0\,\text{L}

, and a temperature of

300\,\text{K}

. The gas is first heated at constant pressure until its temperature doubles. It is then compressed isothermally until its volume is

2.0\,\text{L}

. What is the final pressure of the gas after the two-step process? (a)

1.8\,\text{atm}

(b)

3.6\,\text{atm}

(c)

1.2\,\text{atm}

(d)

2.4\,\text{atm}
