Physical and chemical changes

By:Mackenzie Myers

Physical property

What is it?

A characteristic of a substance that can be observed without changing the substance into something else.


Physical property are used to observe and describe matter.

The three states of matter are: solid, liquid, and gas. The melting point and boiling point are related to changes of the state of matter.

Picture-A physical property of the broccoli is that it's green

Chemical property

What is it?

A characteristic that is observed when a substance interacts with with another substance.

Example-flammability,heat of combustion,rusting

Atoms create Chemical properties.A chemical property is I defined by an objects ability to change given the right conditions

Picture-a chemical property of the match is flammability

Physical change

What is it?

A change that alters the form or appearance of a substance but does not make the material into another substance.

Physical changes are related to physical properties since some measurements require changes be made

Example-melting a ice cube,boiling water,crushing a can

Chemical change

What is it?

A change in matter that produces new substances

The five indicators are-change of color,change of odor,change in temperature,new substance formed, and gas produced

In a chemical reaction,the modules of one substance break apart and join together with another substance to create another compound

Example-mixing baking soda and vinegar together, baking a cake,rust of iron
