Anything hat had mass and takes up space

15

Meniscus

The curve at the surface of a liquid

16

Weight

The measurement of gravitational force on an object

17

Inertia

The tendency of an object to resist a change in motion

18

Physical property

Characteristics of a substance or element like color, density, hardness, etc.

19

Physical change

A change of matter from one form to another without a change in chemical properties

20

Chemical property

Describes matter based on it's ability to change into new matter that has different properties
