Matter changes states during fusion and vaporization. How is this related to heat?

When you heat up water, it starts to evaporate slowly into the air. When you fuse two things together, that takes a lot of heat to do. Both of these things are related to heat.

Explanation:

At the point when you heat up water, it begins to vanish gradually into the air. At the point when you intertwine two things, that takes a great deal of warmth to do. Both of these things are identified with heat.

Explanation:

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
