Question

Based on the results of this lab, write a short paragraph that summarizes how to distinguish physical changes from chemical changes.

Answer 1

A physical change is reversible, a substance change isn't. A physical change is an adjustment in which no new substance is shaped; a synthetic change brings about the arrangement of at least one new substances

Answer 2

Physical changes occur when the properties of a substance are retained and/or the materials can be recovered after the change. Chemical changes involve the formation of a new substance. Formation of a gas, solid, light, or heat are possible evidence of chemical change.
