Vocabulary 7

Physical change:A change in size,shape,or state,without forming a new subtance.Physical changes include separating matter into different parts or mixing matter with new parts as long as  no new subtances are made.

Chemical change:A change in matter that produces a new subtance with different properties from the original.The changes in the liking patterns of the atoms create new subtances.

Chemical reaction:A chemical change of original subtances into one or more new subtances.

Reactant:One of the of the original subtances before a chemical reaction takes place.

Product:One of the new subtances produced when a chemical reaction takes place.

Vocabulary 6

Mixture:Two or more parts blended together yet keeping their own propertiesand not turning into a new subtance.

Solution:A mixture in which subtances are completely blended so that properties are the same throughout and the subtances styay blended.

Suspension:A mixture of subtances that separate upon standing.

Colloid:Particles (or droplets)large enough to block out light spread throughout another subtance.

Emulsion:A liquid spread throgh another liquid.

Aerosol:Liquid drops or solid particles spread through a gas.

Gel:A solid spread through a liquid.

Foam:A gas spread through a liquid or solid.

Vocabulary 5

State of matter:Any of the forms matter can exist in.Adding or removing heat can make subtances change from one subtance into another.

Melting point:The temperature at which a solid changes state into a liquid.

Boiling point:The temperatura at which aliquid change state into a gas.The boiling point have their own temperature.

Freezing point:The temperature at which  a liquid changes satate into a solid.

Vocabulary 4
