Work Done Through Multiple Processes
Multiple Choice
Multiple ChoiceA gas with an initial volume of 0.2 m3 is heated at constant volume, and the pressure increases from 2×105 Pa to 5×105. Then, it compresses at constant pressure until it reaches a final volume of 0.12 m3. Draw the two processes in the PV diagram below and find the total work done by the gas.
A
- 1.6 × 104 J
B
4 × 104 J
C
0 J
D
- 4 × 104 J
