Question

true
false
rewatch submit

Explanation:

A physical change is a change in which no new substances are formed. Phase changes (like melting, freezing, vaporization, condensation, sublimation, and deposition) are physical changes. Since no new substances are created during a phase change, the original substance can be recovered by reversing the conditions (e.g., melting ice (solid - liquid) can be reversed by freezing the water (liquid - solid)).

Answer:

True
