Physical Properties of Matter

Matter

• Matter is any living or non-living thing in the universe
• All objects, things, plants, people, animals, etc are made up of matter
• Anything that has mass and occupies space is matter – even the air you breathe is matter

Properties of Matter

Properties are characteristics used to describe something.

Properties can be used to help identify a substance.

Properties of Matter

• Physical properties of matter are used to observe and describe matter.
• Physical properties can be observed without changing the matter's composition (the make up of matter)

List of Physical Properties:

These are some of the physical properties of matter:

Appearance
Mass
Magnetism
Relative Density
Solubility
Color
Odor
State of Matter
Ability to conduct or insulate

Observations

• Some physical properties are easily observed.
• Others require a tool for measurement such as mass or temperature.

Mass

• Mass is the amount of matter in an object.
• Mass is similar to weight, but they are not the same thing.
• To measure the mass of an object, you can use a balance scale.
• Mass can be measured in grams or kilograms.

Magnetism

• Magnetism is a physical property that can be tested by using a magnet
• If an object is attracted (can be picked up) by a magnet, then it has magnetism
• Only a few metals are magnetic – iron, nickel, and cobalt, and mixtures of those metals have magnetism

State of Matter

• State of Matter is also a physical property that can be used to describe matter.
• There are 3 states of matter that you need to be familiar with:

1.Solid

2.Liquid

3.Gas

Relative Density

• Relative density is a physical property which can be used to describe whether an object will sink or float in water.
• If the object is more dense than water, it will sink.

• If the object is less dense than water, it will float.

Solubility

• Solubility refers to the ability of a substance to be dissolved in another.
• We will look at solubility in water – How much of a substance can be dissolved in water?
• Solubility depends on the amount of the substance and the temperature of the water.

Warm water

• Warm water will allow some substances to dissolve more rapidly.
• Salt will dissolve in room temperature water, but dissolves faster in warmer water.
• Once dissolved, the salt is invisible, but if you taste the water, you will know it is still there!
