When 1 mole of gas is heated at constant volume, the temperature rises form 273 ~K to 546 ~K . If heat supplied to the gas is xJ , then find the correct statement from following.

Options

  1. AQ = U = x , W =0
  2. BQ = W = x J, V =0
  3. CV =0, Q = W =- x J
  4. DQ =- W = x J, V =0

Correct answer

A. Q = U = x , W =0

Step-by-step solution

W =- Pext. V Due to constant volume V =0, ~W =0 q=x J First law of thermodynamics, aligned & U = q + w & U = xJ = q aligned
