Question: A monatomic gas undergoes a process given by 2dU+3dW=0, then the process is

Options:

A) isobaric

B) adiabatic

C) isothermal

D) none of these

Show Answer

Answer:

Correct Answer: B

Solution:

[b]dQ=dU+dW=dU2dU3=dU3

=13nCυdT=13n32RdT=nRdT2

C=1ndQdt=R2

Which is not equal to 0, infinity or 5R/2.
