An Expansion Process on an Ideal Diatomic Ideal Gas Has $p V$

question 50

Multiple Choice

An expansion process on an ideal diatomic ideal gas has a linear path between the initial and final coordinates on a $p V$ diagram. The coordinates of the initial state are: the pressure is $300 \mathrm { kPa }$ , 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? $( R = 8.31 \mathrm {~J} / \mathrm { mol } \cdot \mathrm { K } )$

• A) \(19,000 \mathrm {~J}\)
• B) \(13,000 \mathrm {~J}\)
• C) \(6300 \mathrm {~J}\)
• D) \(16,000 \mathrm {~J}\)
• E) \(9400 \mathrm {~J}\)
