What is physical property.
What is density and what is one way you can find it?
What is the amount of matter present in a certain volume of a substance. Density=mass/volume.
In each test (experiment), you can change only one thing. We call this the ____________.
What is a variable?

Define condensation and evaporation.
What is condensation is the process by which a gas changes into a liquid. Energy is removed from the gas.
Evaporation is the process by which a liquid changes into a gas and energy is added.
