Which describes the role the particles of objects play in attaining thermal equilibrium?

Question

anonymous · Answer

A.
Colliding particles exchange kinetic energy until particles in both the warm and cold object move at the same rate.
 
 B.
Colliding particles absorb heat energy from the air until particles in both the warm and cold object reach the same level of thermal energy.
 
 C.
Colliding particles absorb thermal energy from the air until particles in both the warm and cold object reach the same temperature.
 
 D.
Colliding particles exchange potential energy until particles in both the warm and cold object reach the same temperature.

Oh, yeah, I think I read the answers wrong anyway. Average kinetic energy would equal the same temperature, so the particles want to have the same average kinetic energy.
