| What happens to energy during phase change? |
|
Definition
a change that occurs when potential energy of a phase changes and particles spread/arrangement changes; during a phase change temperature remains constant
Remember "P-P"==> Phase change = Potential energy change |
|
|
Term
|
Definition
do no change, even if the amount of substance changes
like: density, melting point boiling point, conducticity |
|
|
Term
|
Definition
do CHANGE depending on the amount of substance,
like: melting time, boiling time, length, volume, mass |
|
|
Term
