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

Options

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

Correct answer

D. q=0,ΔT=0,w=0\mathrm{q}=0, \Delta \mathrm{ T}=0, \mathrm{w}=0

Step-by-step solution

ΔU=q+w\Delta U=q+w For a adiabatic process, Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following: Δ\Delta\mathrm{U}=\mathrm{w}=−pexΔv=-\mathrm{p}_{\mathrm{ex}} \Delta \mathrm{v} For free expansion of ideal gas p0=0\mathrm{p}_0=0Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following: As Δ\Delta\mathrm{U}=\mathrm{C}ΔT=0\Delta \mathrm{T}=0Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following:
