2. What is Matter? Matter is anything that has mass and volume
Solid, Liquid, and Gas are the three states of Matter

3. What is the Kinetic Molecular Theory?
This theory describes how changes in the kinetic energy of particles can result in changes of state
This theory also helps explain the difference between solids, liquids, and gases
It explains what happens to matter when the kinetic energy of particles changes
Main points of kinetic molecular theory are:
All matter is made up of very small particles
There is empty space between particles
Particles are constantly moving
Energy makes particles move

4. What is chemistry?
Chemistry includes facts and observations about matter.
Chemistry involves changes such as Chemical and Physical change
Chemical change is a change in matter that occurs when substances combine to form new substances
Physical change is when appearance of substance may change, but the chemical substance remains the same and that no new substances are formed

5. How does the states of Matter change?
There are a number of factors that could change the state of Matter such as temperature.
If a solid such as an ice cube was put in a location with an inconsiderable amount of heat, the ice cube’s state will change into liquid(water). This is called melting.
If a liquid such as water were to experience an immense amount of heat, the water will turn into gas(steam). This is called evaporation.
If a liquid such as water was left inside a refrigerator for a long time, the water will turn into a solid(ice cube). This is called Freezing.
These are one of the ways that temperature can change the state of Matter.

6. What are the Physical Properties of Matter?
Qualitative properties
Quantitative properties
Qualitative Properties can be described but not measured such as:
State- solid, liquid, gas
Colour- colour
Malleability- the ability to be bent into sheets
Ductility- the ability to be drawn into wires
Crystallinity- the shape or appearance of a crystal
Magnetism- the tendency to be attracted to a magnet
Quantitative Properties can be measured with numbers such as:
Solubility- the ability to dissolve in water
Conductivity- the ability to conduct heat or electricity
Viscosity- the resistance to flow
Density- the ratio of a material’s mass to its volume
Melting/Freezing point- the temperature of melting/freezing
Boiling/Condensing point- the temperature of boiling/condensing
