What is matter?
A substance made of only one type of atom.
What is an element?
Ice cream melting

Energy of motion
The base unit for measuring mass.
What is gram?
Particles that can move around each other, but are still close together.
What is a liquid?
Two or more atoms bonded together.
What is a molecule?
Gas production, precipitate formation, color change, temperature change, property change, odor change
What are evidences for a chemical reaction?
What is potential energy?
This refers to how tightly packed an objects particles are and impacts whether an object will float or sink.
What is density?
The process of particles increasing their motion and moving from a liquid to a gas.
What is evaporation?
Two or more different atoms bonded together.

What is a liquid?
These elements on a periodic table all react similarly with other substances.
What is a group or family?
