An ideal gas may expands from V(0) to 2V...

An ideal gas may expands from `V_(0)` to `2V_(0)` according to following three processes. Molar specific heat for processes `b` will be

A

positive if `a` is isothermal and `c` is adiabatic processes

B

negative if `a` is isothermal and `c` is adiabatic processes

C

positive if `c` is isothermal and `c` is adiabatic processes

D

negative if `c` is isothermal and `a` is adiabatic processes

Text Solution

Verified by Experts

The correct Answer is:
B
If a is isothermal and `c` is adiabatic processes then for `b DeltaU` will be negative and `Q` be positive so specific heat will be negative.
