Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following:

Options

  1. Aq =0, ~T 0, w =0
  2. Bq=0, T 0, w 0
  3. Cq = 0, ~T =0, w =0
  4. Dq =0, ~T =0, w =0

Correct answer

D. q =0, ~T =0, w =0

Step-by-step solution

U=q+w For a adiabatic process, U = w =- p _ ex v For free expansion of ideal gas p ₀=0 As U = C T =0
