Thermodynamics

The correct option for the free expansion of an ideal gas under adiabatic conditions is:

  1. A.q=0, ΔT=0q = 0,\ \Delta T = 0 and w=0w = 0✓
  2. B.q=0, ΔT<0q = 0,\ \Delta T < 0 and w>0w > 0
  3. C.q<0, ΔT=0q < 0,\ \Delta T = 0 and w=0w = 0
  4. D.q>0, ΔT>0q > 0,\ \Delta T > 0 and w>0w > 0

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
