What is matter?
Anything that has mass and takes up space.
What is evaporation?
Vaporization that takes place only on the surface of a liquid.
What is a substance?
A single kind of matter that always has a specific makeup or composition.
What is mass, volume, and weight?
1 Mass - amount of matter in an object.
2 Volume - amount of space that matter occupies.
3 Weight - measure of the force and gravity on an object.
What is thermal energy?
Total kinetic energy and potential energy of all particles in an object or substance.
Pressure= Force / Area

What is thermal energy?
Total kinetic energy and potential energy of all particles in an object or substance.
A characteristic that can be observed without changing the matter into another type of matter.
What is a physical property?
A substance made of two or more elements that are chemically combined in a set ratio.
What is a compound?
The measure of the average kinetic energy of the particles in an object or substance.

What is a manipulated / independent variable?
Characteristic that describes something’s ability to become something else.
What is a chemical property?
Substances that are made up of only one type of atom.
What are elements?
An inward force, or pull, among the molecules in a liquid that brings the molecules on the surface closer together.
What is surface tension?
The factor that may change in response to the manipulated variable.
What is a responding/dependent variable?
The basic unit from which all matter is made.
What is an atom?
Made up of two or more substances that are together in the same place, but their atoms are not chemically combined.
