• The one with WEAKER attraction it is now a LIQUID.

• The one with WEAKER attraction it is now a GAS.

• The one with STRONGER attraction it is now a gas.

Suppose you pour a glass of ice water and set it on the kitchen table. After a few minutes, the outside of the glass will be covered with drops of water. Why did this happen?

• Oxygen in the air cooled and condensed onto the cold glass.

• Water vapor in the air cooled and condensed onto the cold glass.

• Water vapor in the air cooled and evaporated onto the cold glass.

• Water seeped through pores in the glass.

When heat is added to a liquid, what occurs?

• Liquid molecules begin to condense to form a solid.

• Liquid molecules are being slowed down to become a gas.

• Liquid molecules speed up and begin to spread out to become a gas.

• Liquid molecules begin to slow down to become a solid.
