100

In this state of matter, the particles are packed closely together.

What is a solid?

100
This is the energy of motion - also the reason for the title of this category.
What is kinetic?
100
This is the phase change that occurs when ice melts.
What is melting?
100
These state of matter can be described as fluids.
What is liquid and gas?
100

This is the way you calculate the density of an object.

What is mass divided by volume?

200

In this state of matter, the spaces between the particles is large

What is a gas?

200
This is what exists between particles.
What is empty space?
200
This is the phase change that occurs that results in water forming on cold pipes in a washroom.
What is condensation?
200

This can be determined because oil floats on top of water.

How you know oil is less dense than water?

200
This is the word used to describe the rise in water level in a graduated cylinder when a solid object is placed inside it.
What is displacement?
300

These states of matter have a defined volume.

What is solid and liquid?

300

This is the type of motion in particles in a solid.

What is vibration?

300
This is the phase change that occurs when a glass of water left out in the sun dries up.
What is evaporation?
300

This is why hot air balloons float.

What is a result of hot air being less dense than cold air.

300
If a solid object has a mass of 10 grams and a volume of 2 cm3, this is the density of this object?
What is 5 g / cm3?
400

In these states of matter, there are noticeable attractive forces.

What is solid and liquid?

400

The more of this that particles have, the faster they move and the smaller attractive forces between them.

What is energy?

400
This is the phase change that occurs when snow disappears on a sunny, cold winter day.
What is sublimation?
400

This is the reason breezes or wind exists.

What is the movement of particles from hot air to cold air?

400
If you place a chunk of pure copper in a graduated cylinder and the water level rises from 50 mL to 52 mL and the mass of the copper is 18 grams, this is the density of copper.
What is 9 g / mL?
500
This is the term used for the total energy inside of a solid, liquid or gas.
What is thermal energy?
500

This is the word used to describe the average energy that each particle in a substance has.

What is temperature?

500
This is the phase change that describes frost on your lawn.
What is deposition?
500

This contributes to changes in weather.

What is differences or changes in air density?

500
This is the mass of a gold nugget if the density of gold is 19 g/cm3 and the volume is 2 cm3.
