Physical Changes & Properties

By: Emily Han & Hannah Yao

What is a physical change?

A physical change does not produce a new substance, but changes in state or phase. Although they may look different, the starting and ending materials are the same.

Remember that the size, shape, and phase of matter (solid, liquid, gas) changes.

EXAMPLES: Crushing a can, melting an ice cube, boiling water, mixing sand and water, breaking glass, shredding paper, etc.

What is a physical property?

A physical property is an aspect of matter that can be observed or measured without ever changing it to something else.

Examples: Volume, temperature, length, melting point, color, shape, density, appearance, texture, odor, etc.
