Physics Thermodynamics Cyclic Process MCQ (Single Correct)

A ideal gas undergoes a cyclic process abcda which is shown by pressure-density curve -

Work done by the gas in the process 'bc' is zero

Work done by the gas in the process 'cd' is negative

Internal energy of the gas at point 'a' is greater than at state 'c'

Net work done by the gas in the cycle is negative

Text Solution

The correct answer is:

CHECK THE SOLUTION.

(a, b, d)

P = RT ⇒

Slope of the curve ∝ Temperature. Hence and ab are isothermal processes ∝

i.e. bc and da are constant volume process
