Question 185 of 200

Multiple Choice

Isobaric

7.75%

Explanation:

Isochoric

57.64%

Explanation:

In isochoric process, volume remains constant.

As, W = PΔV

V =constant

ΔV = O

So, W =O.

Thus, is isochoric process, no external work is done.

Hence, option B is correct.

Isothermal

7.64%

Explanation:

Adiabatic

26.98%
