Phases of Matter

When particles lose energy and change from a gas to a liquid it is called ...........

• condensation
• melting
• evaporation
• dissolving

Energy always travels from high to low.

• True
• False

Bonds are the strongest within this phase.

• solid
• liquid
• gas
• polimers

How are liquids and solids different than gasses?

• Gasses have space between their particles.
• Only solids and liquids can be compressed.
• Solids hold the shape of the container they are in.
• Solids and liquids cannot be contained.

Both the melting point and __________ point occur at the same temperature.

• condensation
• boiling
• freezing
• sublimation

Both the boiling point and __________ point occur at the same temperature.

• condensation
• deposition
• freezing
• sublimation

During the process of sublimation...

• a solid turns directly into a gas
• a liquid turns to a gas
• a solid turns into a liquid
• a gas turns directly into a solid

As particles are heated they will

• contract

• expand

As particles are cooled they will

• contract

• expand

Energy(heat) is added in order to go from ...

• solid to gas
• liquid to solid
• gas to liquid
• gas to solid
