A Gas Expands from an Initial Volume of 0

Multiple Choice

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 by the gas during this expansion?

A) 5.2 kJ
B) 7.5 kJ
C) 7.8 kJ
D) 11 kJ
E) 12 kJ
