Heating cheese so that it spreads over the surface of hot food involves which change state?

Heating cheese so that it spreads over the surface of hot food involves a change of state from solid to liquid.

Here's why:

* Solid: Cheese in its original form is a solid, with a defined shape and structure.

* Liquid: When heated, the molecules within the cheese gain energy and move faster, causing the cheese to soften and become more fluid. This allows it to spread out over the surface of the hot food.

This process is called melting.
