हिन्दी

A thermodynamic system is taken through the cycle \( abcda \). The work done by the gas along the path \( bc \) is :

  1. A
    -90 J
  2. B
    -60 J
  3. C
    zero
  4. D
    30 J

Correct answer · Option C

zero

Explanation

Along path \( bc \), the volume remains constant (\( V = 400\text{ cm}^3 \)), making it an isochoric process where \( dV = 0 \). Work done \( W = \int P dV = 0 \).
