According to the particle model theory, what happens to particles when they are cooled?
Particles move farther apart and form a gas state.
Particles remain in the same state.
Particles break apart and form a liquid state.
Particles move closer together and form a solid state.

What is a responding variable?
is what changes as a result of the manipulated variable.
is a part of an experiment that you can change to see how other variables respond.
The height of the object
The width of the object
Quantitative is something you can (a) and qualitative is something you (b)
What is a Manipulated variable?
The object of what you are testing
It is a part of an experiment that you can change to see how other variables respond.
Its what changes as a result of the manipulated variable.
The length of the experiment
What is a controlled variable?
(a)
What is a hypothesis? What makes a hypothesis complete (key words).
(a)
Question meaning in a experiment.
Ask how or why something happens.
Raising your hand
Taking notes after the experiment.
You going to give me cheeseburgers?
Observation meaning
After a experiment you keep track of what you discovered ( taking notes, measuring)
A educated guess in what is going to happen in a experiment
When you ask questions before the experiment has started and answer the when you have completed the experiment.
I have no clue I want cheesburgers.
Celsius scale
Kelvin scale
CHEESEBURGERS
scale based on 0° for the freezing point of water and 100° for the boiling point of water.
A device that measures heat technology( just like a sensor) through out the universe.
Liquid into gas is called = (a)
Gas into liquid is called= (b)
Liquid into solid is called = (c)
Solid turns into gas is = (d)
Gas turning into solid is called = (e)
What is heat?
When particles move faster and generate more energy.
A type of gas
Microwaves
Heat is basically something melting.
Explain STAMP (particels)
S = (a)
T = (b)
A = (c)
M = (d)
P = (e)
Gas has a ton of space. Always moving. A ton of energy and attraction.
NO it has a little amount of space
False
True
No it has less attraction
Solid has no movement or energy at all. Solid has a ton of attraction and no space.
True
False
Particles are ALWAYS pure
True
False
Liquid has a limited amount of space ( they can slide past each other). They have less energy and movement than gas. Has more attraction that gas.
True
False
No they have more space than gas
