Chemistry Made Simple : Matter

Matter :

Anything that occupies space and has mass is called Matter.

Mass:

The quantity of matter which a substance posseses is called Mass.

Inertia:

The property of mass to resist a change of its position or motion is called Inertia.

Density:

Is defined as relationship of mass to its unit volume.

Denoted by D , D = m/V

where D is density, m is mass and V is volume of the substance.

Unit of mass in chemistry is Gram / g and Volume is cm3 / cubic centimeter or milliliter.

States of Matter:

Matter has 3 states:

Solid : has a definite size and a definite shape.

Liquid has a definite volume but takes the shape of the container

Gas has neither a definite shape nor a definite volume.

These three states are interchangable .
