6.15) At constant temperature, a sample of helium gas expands from
922 mL to 1.14 L against a pressure of 2.33 atm. Find w (in J) done
by the gas (101.3 J=1 atm-L).
6.16 The external pressure on a gas sample is 2660 mmHg, and
the volume changes from 0.88L to 0.63 L at constant temperature.
Find w (in kJ) done on the gas (1 atm·L = 101.3 J).
