Question

One mole of an ideal monoatomic gas goes through a cycle in a heat engine process z is isobaric, process x is isochoric,and process y is adiabatic.Find

1. The heat absorbed or release

2. The change in internal energy

3. The work done for each of the three processes and the whole cycle.

Answer 1

Gives

n=1mol

heat engine process

z is isobaric,

process x is isochoric,

and process y is adiabatic.

(1)Heat release

∆Q=∆U-∆W

(2)

Change of internal energy

$U=\frac{3}{2}NKT$

(3)

The work done for each of the three processes and the whole cycle depend on process
