Problem

One mole of an ideal gas at

300\,\text{K}

expands isothermally from an initial volume of

0.50\,\text{m}^3

to a final volume of

1.36\,\text{m}^3

. (Take

R = 8.31\,\text{J mol}^{-1}\text{K}^{-1}

.) How much heat is absorbed by the gas during the expansion? a)

0\,\text{kJ}

-2.5\,\text{kJ}

2.5\,\text{kJ}

1.1\,\text{kJ}
