Matter and Energy

matter

• anything that has weight and takes up space

• a substance that can be seen but not touched

• a type of energy that can be measured

• a concept that exists only in theory

properties

• characteristics or attributes (describes matter)

• physical changes in matter

• chemical reactions of substances

• the state of matter at a given temperature

physical state

• a form of matter: solid, liquid, or gas

• a measure of temperature

• a type of chemical reaction

• a classification of energy

condensation

• the change of gas to liquid

• the change of liquid to gas

• the change of solid to liquid

• the change of gas to solid

evaporation

• the change of liquid to gas

• the process of freezing

• the transformation of gas to liquid

• the mixing of different liquids

mixture

• when different types of matter can be mixed but still retain their shapes

• a combination of substances that results in a new chemical compound

• a process where matter changes its state completely

• a homogeneous blend of materials that cannot be separated

solutions

• a combination of two or more substances that can only be separated through evaporation

• a mixture that can be separated by filtration

• a homogeneous mixture of two or more substances that can be separated by distillation

• a chemical reaction between two or more substances

solubility

• The ability of a substance to conduct electricity.

• The measure of how well something can dissolve in another.

• The process of separating a mixture into its components.

• The ability of a substance to change its state.

density

• the amount of matter in an object compared to the space it takes up; can determine if things sink or float

• the measure of how much space an object occupies

• the total weight of an object regardless of its size

• the ability of an object to conduct heat or electricity

conductivity

• how well something can allow electricity to flow through it

• the ability of a material to resist electrical flow

• the measure of a material's thermal insulation

• the capacity of a substance to store electrical charge
