States of Matter

Matter consists of

• electrons

• protons

• atoms

• molecules

• all of the above

Matter can take many forms, such as

• solid

• liquid

• gas

• all of the above

• none of the above

The state of matter in which the molecules/atoms are FURTHEST apart

• solid

• liquid

• gas

The state of matter in which the molecules are CLOSEST together

• solid

• liquid

• gas

This state of matter has no definite shape

• gas

• solid

• liquid

• both gas and liquid

When a liquid gains energy and becomes a gas it is called

• melting

• freezing

• vaporization

When a solid gains energy and becomes a liquid it is called

• freezing

• melting

• vaporization

When a gas molecules lose energy and become a liquid it is known as

• vaporization

• condensation

• melting

• freezing

A substance that requires a LOT of energy to vaporize has a relatively ______________________boiling point/ temperature

• low

• high

• moderate (neither low nor high, middle of the road)

A substance that requires a LOT of energy to melt (solid to liquid) has a relatively ___________________ melting point

• high

• low

• moderate (neither high nor low, average)
