Phase Changes

Front 1

boiling

Back 1

steaming or boiling up under the action of heat

Front 2

boiling point

Back 2

the temperature at which the vapor pressure of a liquid is equal to the pressure of the

atmosphere on the liquid

Front 3

condensation

Back 3

the process of reducing gas or vapor to a liquid form

Front 4

evaporation

Back 4

matter after it has changed into vapor

Front 5

freezing

Back 5

when a liquid becomes a solid form due to cold tempuratures

Front 6

freezing piont

Back 6

the point where the

temperature has reached a

level of cold that a liquid can turn into a solid

Front 7

melting

Back 7

the process of a solid turning into a liquid after becoming exposed to

elevated tempuratures

Front 8

melting point

Back 8

the point where the

temperature becomes heated enough to change a solid into a liquid

Front 9

sublimination

Back 9

when molecules of a solid gain enough energy and go directly from a solid to a gas, never entering the liquid phase

Front 10

vaporization

Back 10

the rapid change of water into steam, especially in a boiler
