What would be the amount of heat absorbed in the cyclic process shown below?

Options

  1. A5 ~J
  2. B15 ~J
  3. C25 ~J
  4. D100 ~J

Correct answer

D. 100 ~J

Step-by-step solution

In a cyclic process, internal energy change =0 According to 1^ st law of thermodynamics U= q+ W As, U=0, q=- W From the graph, work done = W= Area under curve Here, area of circle = r^2 aligned & = ( 25-5 2 )^2= 10^2 q & =100 ~J aligned
