One mole of an ideal gas goes from an initial state A to final state B via two processs : It first undergoes isothermal expansion from volume `V` to `3 V` and then its volume is reduced from `3 V` to `V` at constant pressure. The correct `P-V` diagram representing the two process in (figure)

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
On `P-V` diagram, isothermal process is represented by rectangular hyperbola. Isobaric process is straight line parallel to volume axis.

One mole of a monatomic ideal gas has an initial pressure, volume, and temperature of P_0 , V_0 , and 438 K, respectively. It undergoes an isothermal expansion that triples the volume of the gas. Then, the gas undergoes an isobaric compression back to its original volume. Finally, the gas undergoes an isochoric increase in pressure, so that the final pressure, volume, and temperature are p_0 V_0 and 438 K, respectively. Find the total heat for this three-step process, and state whether it is absorbed by or given off by the gas.
