Question : 34 of 69

Marks: +1, -0

Solution:

A) Process-I is not isochoric, V is decreasing .

B)Process-II is isothermal expansion

\Delta U=0, W > 0\;\;\;\Delta Q > 0

C)Process-IV is isothermal compression ,

\Delta U=0, W < 0\;\;\Delta Q < 0

D) Process-I and III are NOT isobaric because in isobaric process

T \propto V

hence isobaric T-V graph will be linear.
