Matter
What is the definition of matter?
Anything that takes up space and has mass.
Adding or taking this away causes matter to change its state.
Heat
Burning, cooking, rusting, rotting, or bleaching are examples of what type of change?
Chemical Change
Property that allows heat or electricity to flow through through it.
Conductor
What is the scratch test?
Hardness
What is the definition of mass?
The amount of "stuff" in an object.
When heat is taken away from the liquid, the particles slow down and move closer together. What is this process called?
Freezing
Cutting, tearing, breaking, and painting are examples of what type of change?
Physical
To decide if the change can be undone.
If an object is reflects light (shiny), it has this physical property.
Luster
Name an example of a solid, liquid, & gas.
When heat is added to a solid, the particles speed up and move farther apart. What is this process called?
Melting
A change in state is always this type of change.
(solid -> liquid -> gas -> liquid -> solid)
Physical Change
The temperature at which a solid changes into a liquid
Boiling Point
What is one way you could undo a chemical change?
Gas
When heat is added to a liquid, the particles move faster and farther apart. What is this process called?
Evaporation
can be measured and observed using the 5 senses and will not change the identity of the substance.
Physical Change
A property that pulls metal objects towards one another. Is attracted to cobalt, iron, and nickel.
Magnetism
What is the energy of moving particles called?
Thermal Energy
When heat is taken away from a gas, the particles slow down and move closer together. What is this process called?
Condensation
A change that happens when matter reacts with something and is changed into a different substance.
Chemical Change
The ability of one substance to dissolve into another substance.
Solubility
The 4th state of matter few people know about.
