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.
A substance is able to flow freely within a container. What state of matter is the substance in?

What are the characteristics of a solid?
Solids do not have a definite shape but have a definite volume
Solids have a definite shape and no definite volume
Solids do not have a definite shape and no definite volume

Why do atoms in a solid still vibrate?
All solids have some thermal energy.
Some solids have some thermal energy, and some do not.
Atoms in a solid do not vibrate.
None of the above.
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.
What happens to molecules as temperature and energy increase?
Matter condenses
Substances expand when heated
Atoms become less active
Phase change slows down
Alex noticed that a metal door that sticks on hot days does not stick when it cools off at night. This is because the metal contracts as it cools. The reason for this is that, as the metal cools, the atoms
become smaller and take up less space.
slow down and move closer together.
merge together to form fewer atoms.
speed up and move farther apart.
When heat energy and temperature are at their lowest, what state of matter is a substance in?
Gas
Vapor
Solid
Liquid
A plasma can be made in a laboratory by
cooling a gas to very low temperatures
cooling a gas and reducing the pressure
heating a gas to extremely hot temperatures
heating a liquid to the point it turns into a gas
