Properties of matter that can be observed with out changing the chemical structure
What are Physical Properties?
100

These are the three subatomic particles of an atom

What are protons, neutrons and electrons?

100
All of the waves on the EM spectrum come from
What is the sun?
100
Energy of motion
What is kinetic?
100
This is defined as any push or pull
What is a force?
200
This property of matter is found by dividing mass and volume
What is density?
200

Describe the motion of particles in a solid, liquid and gas

Solid - vibrate in place/tightly held together

Liquid - can slide past each other

Gas - move around freely

200
Mechanical waves need a _________, while EM waves do not
What is a medium?
200
When energy is in one form and changes to another we call it
What is an energy transformation?
200
There will only be motion when two forces are 
What is unbalanced?
300
Rusting and other forms of oxidation are a type of this
What is a chemical change?
300

The periodic table is in order by increasing this

Atomic Number, Number of Protons

300
Opaque objects do this with light
What is absorb it?
300
When you eat food in order to move around this energy transformation is taking place
What is chemical to kinetic?
300
You have weight when you are on Earth but in space you do not. Why?
Weight is a product of gravity
400

This type of matter is formed with two substances are chemically combined together; it's an example of a pure substance

What is a compound?

400
Periods, or rows, on the periodic table describe this, and groups, or columns, describe this
Periods = number of electron shells/energy levels

Groups = number of valence electrons

400
We see things as particular colors because
A particular wavelength reflects off of the surface to our eyes
400
Heat is moving thermal energy. When you put a pot on the stove what type of heat transfer is heating the pot.
What is conduction because it's touching the burner.
400
What is the formula for finding speed?
Distance / time
500

What is the difference between a physical and chemical property?

You can identify physical properties without changing the substance

500

How do you calculate the number of neutrons in an atom?

Atomic Mass - Atomic Number (number of protons)= Neutrons
500
When EM waves move from space to Earth their speed __________ from a gas to a liquid to a solid. However, when mechanical waves move through a medium their speed _____________ from a gas to a liquid to a solid.
EM = speed decreases

Mechanical = speed increases

500
Two objects of different temperatures are touching. How does the heat move between them and when will it stop?
The heat moves from the warmer object to the cooler and it will stop when they are the same temperature
500
Constant speeds are shown on a graph by this
A straight upward line
