Which of the following set of properties is correct when one mole of a gas is heated keeping volume constant by increasing temperature and supplying 500 J of heat?

Options

  1. Aq = w =500 ~J , U =0
  2. Bq = U =500 ~J , w =0
  3. Cq = U =-500 ~J , w =0
  4. Dq =500 ~J , U = w =0

Correct answer

B. q = U =500 ~J , w =0

Step-by-step solution

Heat is supplied to the system. q=500 ~J At constant volume, V =0 w =- P _ ext ~V =0 According to the first law of thermodynamics, aligned & U = q + w & U=500+0=500 ~J aligned
