Matter
Any thing that takes up space and has mass.
Mass
The amount of matter in an object.
Volume
The amount of space an object
takes up.
Density
Mass divided by volume
Weight
The force of gravity pushed upon you.
Atom
The basic particle from which all elements are made of.
Endothermic
A change in which energy is absorbed.
Exothermic
A change in which energy is released.
Element
A substance that can not be broken down into any other substance by chemical or physical means.
Compound
A substance made of two or more elements chemically combined in a specific ratio, or proportion.
Mixture
Two or more substances that are together in the same place but their atoms are not chemically bonded.
Law of Conservation of Mass
The fact that matter is not created or destroyed in any chemical or physical change.
Thermal energy
The total energy of the motion of all the particles in an object.

List 3 clues that a chemical change might be occurring.
1. Two substances form from one substance.
2. The substance has a different boiling point.
3. The substance is fizzing or bubbling.
Give 5 ways to separate a mixture.
1. Flitration
2. Magnetism
3. Pick it apart by hand
4. Distillation
5. Evaporation
What are the 2 types of mixtures and how do they differ? Give 2 examples of each.
Homogenous and Heterogenous
Homogenous is something that can't be separated from just looking at it a picking it away by hand, but heterogenous is something that you could pick away by hand.

Homogeneous/ Brewed coffee/wine
Heterogeneous/ Soil/sea water
Viscosity
A liquids resistance to flowing.
Surface tension
The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together; causes the surface to act as if it has a thin skin.
Change of state
Change in appearance.
Fluid
Any substance that can flow.
Pressure
The force pushing on a surface divided by the area of that surface.
State Charles’s Law and give an example
A principle that describes the relationship between the temperature and volume of a gas at constant pressure.
State Boyle’s Law and give an example
A principle that ascribes the relationship between the pressure and volume of a gas at constant temperature.
