When an ideal gas undergoes unrestricted expansion
1 Cooling occurs because the molecules lie above inversion temperature
2 No cooling occurs as no attractive interactions exist among molecules
3 Cooling occurs as molecules collide with each other among molecules
4 Cooling does not occur as these do work equal to loss in kinetic energy
Explanation:
As no attractive forces between the particles of ideal gas
