What is an atom?
The force exerted by a gas.
What is pressure?
Separating parts of a mixture through vaporization and condensation.
What is distillation?
What are the actinides?
Features of a substance that can be observed without changing the identity of the substance.
What are Physical Properties?
The smallest particle of a compound, formed when two or more atoms join together and share electrons.
What is a molecule?
A solid changes to a gas in this process.
What is sublimation?
The amount of a substance that can dissolve in another substance is called this.
