Answer to Question #281284 in Molecular Physics | Thermodynamics for Biola

Question

1 mole of an ideal monoatomic gas, goes through a cycle in a heat engine. Process Z is isobaric, process X is isochoric and Y is adiabatic find:-

A. A heat absorb or release.

B. Change in internal energy

C. Work done for each of the three process and the whole cycle.

Answer 1

The heat release:

$$Q=\Delta U-W.$$

Change in internal energy:

$$\Delta U=\frac32 NkT.$$

The work done  for each of the three process and the whole cycle depends on the process. To upload the image, attach a link with the photo uploaded. You may use Google Drive, Microsoft OneDrive, etc to share the image.
