If the heat of 110 J is added to a gaseous system, whose internal energy is 40 J , then the amount of external work done is

Options

  1. A180 J
  2. B70 J
  3. C110 J
  4. D30 J

Correct answer

B. 70 J

Step-by-step solution

Heat added to the system Q=110 ~J Internal energy u=40 ~J External work done is given by W= Q- u=110-40=70 ~J
