What energy source is required to melt chocolate?

During melting, particles
Slow down, contract, and bond tighter to form a solid
Speed up, expand, and bond loosely to form a liquid
During freezing, particles . . .
Speed up, expand, and bond loosely.
Slow down, contract, and bond tightly.
Energy ALWAYS moves from . . .
COLD to HOT
HOT to COLD
WARM to ICE
COOL to SOLID
The reason energy only transfers from hot to cold is because hot particles have more energy to give than cold particles because they move faster.
