question 102

Multiple Choice

An expansion process on an ideal diatomic ideal gas has a linear path between the initial and final coordinates on a pV diagram. The coordinates of the initial state are: the pressure is 300 kPa, the volume is $0.0700 \mathrm {~m} ^ { 3 }$ and the temperature is $390 \mathrm {~K}$ The final pressure is $130 \mathrm { kPa }$ and the final temperature is $310 \mathrm {~K}$ How much work is done by the gas during this process? (R = 8.31 J/mol ∙ K)

• A) 13,000 J
• B) 6300 J
• C) 9400 J
• D) 16,000 J
• E) 19,000 J
