STATE OF MATTERINSTRUCTIONAL MATERIALS
MATTER
Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size.
STATES OF MATTER
Matter occurs in four states: solids, liquids, gasses and plasma. Often the state of matter of a substance may be changed by adding or removing heat energy from it. For example, the addition of heat can melt ice into liquid water and turn water into steam.
CHANGING STATE
The atoms and molecules don't change, but the way they move about does. Water, for example is always made up of two hydrogen atoms and one oxygen atom. However it can take the state of liquid, solid (ice), and gas (steam). Matter changes state when more energy gets added to it. Energy is often added in the form of heat or pressure.
SOLIDS
A solid has a definite shape and volume.
Examples:
1. wood
2. sand
3. steel
4. apple
5. ice
6. rock
7. chair
8. board
9. table
10. pen
LIQUIDS
A liquid has definite volume but takes the shape of its container.
Examples:
1. milk
2. water
3. blood
4. wine
5. honey
6. coffee
7. tea
8. urine
9. gasoline
10. lotion
GASSES
A gas has neither a definite volume nor a definite shape.
Examples:
1. air
2. helium
3. nitrogen
4. freon
5. water vapor
6. oxygen
7. ozone
8. hydrogen sulfide
9.natural gas
10. carbon dioxide
PLASMA
Plasma has neither definite volume nor a definite shape.
Plasma is often seen in ionized gasses. Plasma is distinct from a gas because it possesses unique properties. Free electrical charges (not bounds to atoms or ions) cause the plasma to be electrically conductive.
The plasma may be formed from heating and ionizing a gas.
Examples:
Stars are made of plasma. Lightning is plasma. You can find plasma inside fluorescent lights and neon signs.
