Which of the following is correct option for free expansion of an ideal gas under adiabatic condition?

Options

  1. Aq≠0,ΔT=0,W=0q \neq 0, \Delta T=0, W=0
  2. Bq=0,ΔT=0,W=0q=0, \Delta T=0, W=0
  3. Cq=0,ΔT<0,W≠0q=0, \Delta T < 0, W \neq 0
  4. Dq=0,ΔT≠0,W=0q=0, \Delta T \neq 0, W=0

Correct answer

B. q=0,ΔT=0,W=0q=0, \Delta T=0, W=0

Step-by-step solution

For an adiabatic process, q=0q=0 and for free expansion, W=0,∴ΔT=0W=0, \therefore \Delta T=0.
