Anything that occupies space and has a mass. Composed of atoms, chemical substances that cannot be broken down.

Front 2

Define states of matter

Back 2

*Gas

*Liquid

Front 3

What affects the states of matter?

Back 3

The state of the matter is affected by temperature, the rate at which atoms are moving and the space between atoms in matter.

Front 4

What happens in volume pressure relationships where there is smaller space?

Back 4

Greater pressure by liquid/gas

Back 27

A homogeneous mixture composed of two or more substances.

Front 28

Define solutes

Back 28

Substances present in smaller amounts within a mixture.

Front 29

Define solvent

Back 29

The substance present in the greatest amount in a mixture.

Front 30

Define colloid

Back 30

Substances are medium sized, easily transform between liquid and solid state.

Front 31

Define suspension

Back 31

Solutes are large, solutes are suspended in a mixture, solutes settle out.

Front 32

Define concentration

Back 32

Refers to the amount of solutes within a solvent.

Front 33

Define anabolic reaction

Back 33

Occur when bonds are formed, resulting in the absorption of energy.

Front 34

Define catabolic reaction

Back 34

Occur when bonds are broken, resulting in the release of energy.

Front 35

Define rearrangements

Back 35

Occur when bonds are rearranged between molecules. This type of reaction results in no net change in energy as bonds are both broken and formed.

Front 36

Define energy

Back 36

The capacity to do work, or to put matter into motion.

Front 37

Define kinetic energy

Back 37

Energy in action, causing movement.

Front 38

Define potential energy

Back 38

Stored or inactive, energy that has potential to create movement, but is not currently doing so.

Front 39

Define chemical energy

Back 39

Energy stored in chemical bonds when chemical reactions occur to break bonds, the energy is realised, while the formation of chemical bonds to energy storage.
