analyzing a heating curve phase changes

Thermal energy always moves:

• From a high temperature object to a lower temperature object.

• From a lower temperature object to a higher temperature object.

• From an object with lower kinetic energy to an object with higher kinetic energy.

• From an object of higher mass to an object of lower mass.
