What Is Matter? Matter is anything that has mass and takes up space.
Matter in the Universe Everything in the universe that you can see is made up of some type of matter.

Matter and Volume
Liquid Volume Liters (L) and milliliters (mL) are the units used most often to express the volume of liquids.

4. Volume = length  width  heighth

Volume of a Regularly Shaped Solid Object To find the volume of a regularly shaped solid object use the following equation:
Volume = length  width  heighth
Volume of an Irregularly Shaped Solid Object You can find the volume of an irregularly shaped object by measuring the volume of water that the object displaces.

Section 1 What Is Matter?
Matter and Mass
The Difference Between Mass and Weight Weight is the measure of the gravitational force exerted on an object. The more mass an object has, the greater the gravitational force on the object and the greater the object’s weight.
Measuring Mass and Weight The SI unit of mass is the kilogram (kg). Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N).

Section 1 What Is Matter?
Inertia
What Is Inertia? Inertia is the tendency of an object to resist a change in motion.
Mass: The Measure of Inertia An object that has a large mass is harder to move and harder to stop than an object that has less mass. The reason is that the object with the large mass has greater inertia.

Liquid Layers The graduated cylinder below contains six liquids. Each liquid is a different density so the liquids form layers.
Density of Solids Knowing the density of a substance can also tell you what kind of substance it is.

Solving for Density To find an objects density (D), first measure its mass (m) and volume (V). Then use the following equation:
D = m/V

Comparing Physical and Chemical Properties You can observe physical properties without changing the identity of the substance. Chemicals properties are more difficult to observe.
Characteristic Properties The properties that are most useful in identifying a substance are characteristic properties.

What Happens During a Chemical Change? During a chemical change a substance changes chemical properties.
Signs of Chemical Changes Some common signs of chemical changes includes a change in color, odor, production of heat, fizzing, and so on.
Matter and Chemical Changes Chemical changes change the identity of the matter involved.

A Change in Composition Physical changes do not change the composition of a substance while chemical changes do.
Reversing Changes Many physical changes are easily reversed, but most chemical changes cannot easily be reversed.
