• Solid, Liquid, Gas

• Plasma, Solid, Liquid

• Solid, Liquid, Vapor

• Solid, Liquid, Foam

What is the process of a gas becoming a solid called?

• Condensation

• Sublimation

• Deposition

• Evaporation

What is matter?

• Anything that has mass and takes up space.

• A substance that can be seen but not touched.

• An object that exists only in theory.

• A form of energy that cannot be measured.

What happens to particles in a gas?

• They are tightly packed and vibrate in place.

• They are far apart and move freely.

• They are arranged in a fixed structure.

• They are clustered together and move slowly.

What happens to particles in a solid?

• They are loosely arranged and move freely.

• They are closely packed together and vibrate in place.

• They are spread out and can flow easily.

• They are in a gaseous state and move rapidly.

What is thermal energy?

• The energy that comes from the temperature of matter.

• The energy stored in chemical bonds.

• The energy associated with the motion of particles in a solid.

• The energy released during nuclear reactions.

What is kinetic energy?

• The energy of rest.

• The energy of motion.

• The energy of position.

• The energy of heat.

What happens to particles in a liquid?

• They are far apart and move freely.

• They are close together but can move past each other.

• They are tightly packed and do not move.

• They are in a fixed position and cannot move.

What causes a liquid to change to a gas?

• Increase in thermal energy.

• Decrease in pressure.

• Increase in viscosity.

• Decrease in temperature.

What is an example of a substance that can exist in all three states of matter?

• Oxygen (gas, liquid, solid)

• Water (ice, liquid water, steam)

• Carbon Dioxide (gas, liquid, solid)

• Iron (solid, liquid, gas)
