Problem

An ideal gas at

300\,\text{K}

is initially at a pressure of

5.0\,\text{atm}

and a volume of

2.0\,\text{L}

. It is allowed to expand isothermally until its pressure falls to

2.0\,\text{atm}

. (Use

1\,\text{L atm} = 101.3\,\text{J}

.) a. (i) Calculate the final volume of the gas. b. (ii) Calculate the magnitude of the heat absorbed during the expansion.
