|
|
|
the part of the experiment that makes things happen. it is what is diffrent when setting up the experiment
|
independent variable
|
|
|

|
incresese
|
|
|
particles viberate in place and very close together and have the lowest kinetic energy
|
solid
|
|
|
particles are moving very fast in all dsirection, are very spread out and have a high level of kenetic energy
|
gas
|
|
|
particles move more freely, are a little further apart and have an average amount of kenetic energy
|
liquids
|
|
|
solids change to liquids. energy must be contained
|
melting
|
|
|
gas changes to liquid energy must be released therefore particles slow down
|
condensation
|
|
|
liquid change to solid. Energy must be released therefore particles slow down
|
freezing
