sublimation

Chemical chnage

A change that occurs when one or more substances change into entirely new substances with different properties.

Solute

A substance that is dissolved in a solution.

heat of fusion

Amount of energy required to change a substance from the solid phase to the liquid phase.

condensation

Gas to liquid

evaporation

Liquid to gas

sublimation

Solid to gas

heat of vaporization

The amount of energy required for the liquid at its boiling point to become a gas

Thermal decomposition

The breaking up of a chemical substance with heat into at least two chemical substances.

freezing point

The temperature at which a liquid changes into a solid the temperature at which a liquid changes to a solid

absolute zero

The temperature at which no more energy can be removed from matter

phyiscal change

a change in matter that does not involve a change in the identity of the substance

convection current

a current caused by the rising of heated fluid and sinking of cooled fluid

Deposition

gas to solid

colligative properties

properties of a solution that depend only on the number of particles dissolved in it, not the properties of the particles themselves. The main ones are boiling point elevation and freezing point depression.

Expansion

the act of increasing (something) in size or volume or quantity or scope

kinetic energy

the energy an object has due to its motion

Sublimation

the process in which a solid changes directly into a gas

contraction

the process of becoming smaller

melting point

the temperature at which a given solid will melt.
