A system is taken from state a to state c by two paths adc and abc as shown in the figure. The internal energy at a is . Along the path adc the amount of heat absorbed and the work obtained whereas along the path abc the heat absorbed . The amount of work along the path abc is 10 J 12 J 36 J 6 J
Multiple Choice Options
- A 10 J
- B 12 J
- C 36 J
- D 6 J
Step-by-Step Verified Solution
From first law of thermodynamics
Q a d c = _ U a d c + W a d c
50 J = _ U a d c + 20 J
_ U a d c = 30 J
Again
Q a b c = _ U a b c + W a b c
W a b c = Q a b c _ _ U a b c
W a b c = 36 J _ 30 J
W a b c = 6 J
