Answer 1

Answer:

sublimation

Explanation:

You have observed matter changing state, like when an ice cube melts from a solid into liquid water or the water boils into vapour, but do you know why a substance changes from? This is because the matter is affected by energy. If a substance absorbs enough energy, atoms, and molecules move around more. The increased kinetic energy can push particles far enough apart that they change form. Also, increased energy affects the electrons surrounding atoms, sometimes allowing them to break chemical bonds or even escape the nucleus of their atoms.
