What caused the ice cube to melt? What do you think is happening to the particles on the inside of the ice cube as it melts?

Ice melts when heat is provided to it.

Explanation:

When heat is provided, the kinetic energy of the particles increases. The particles start vibrating. As you keep providing heat, the particles start vibrating more strongly and with greater speed. Some particles become so energetic, that they are able to break the force of attraction and move away as a liquid.

Hope this helps.
