A gas expands from an initial volume of 0.040 m3 to a final volume of 0.085 m3 while its pressure increases linearly with the volume (so that the process follows a straight-line path in a pV diagram) from 110 kPa to 225 kPa.

How much work is done on the gas during this expansion? A) -5.2 kJ
B) -7.5 kJ
C) -7.8 kJ
D) -11 kJ
E) -12 kJ

A) 825 nm
B) 791 nm
C) 757 nm
D) 723 nm
E) 689 nm
