Effects of pressure and temperature on matter

The Kinetic Theory of Matter states that...

• matter is made of small particles that are in constant motion

• matter is made of small particles that never move

• matter is made of large particles that sometimes move

When a solid is heated it's particles begin to vibrate with energy

• true

• false

What is the melting point?

• Temperature solid changes to gas

• Temperature liquid changes to gas

• Temperature solid changes to liquid

Evaporation is when liquid particles get enough energy they begin to escape

• True

• False

What is the boiling point?

• The temperature a gas changes to a liquid

• The temperature a liquid changes to a gas

• The temperature a solid changes to a liquid

What is sublimation?

• When a solid changes to a liquid

• When a solid changes to a gas

• When a gas changes to a solid

Solids are effected a lot by pressure

• True

• False

What happens when pressure is applied to a container of gas?

• The particles expand

• The particles vibrate

• The particles get closer together

A gas can change to a liquid if a lot of pressure is applied

• True

• False

Choose the correct statement(s) about how pressure can effect changes of states of matter

• If pressure if lower, you need a higher temperature to change the state of matter

• If the pressure is higher, you need a higher temperature to change the state of matter

• If pressure if lower, you need a lower temperature to change to state of matter
