Curve in the figure shows an adiabatic compression of an ideal gas from `15m^3` to `12m^3`, followed by an isothermal compression to a final volume of `3.0m^3`. There are 2.0 moles of the gas. Total heat supplied to the gas is equal to: (ln2= 0.693)

A

4521 J

B

`-4521J`

C

`-6653 J`

D

`-8476 J`

Text Solution

Verified by Experts

The correct Answer is:
C
There is no heat transfer in adiabatic compression. In isothermal process
`Q=W=P_(1)V_(1) ln. (V_(2))/(V_(1))=400xx12 ln 1/4 =-6653 J`

An ideal monoatomic gas occupies volume 10^(-3)m^(3) at temperature 3K and pressure 10^(3) Pa. The internal energy of the gas is taken to be zero at this point.

Plot the process on a PV diagram. Calculate (i) The work done and the heat transferred in each process and the internal energy at the end of each process, (ii) The thermal efficiency of the cycle.
