what is freezing?

The change of state from liquid to solid is called freezing.

100

what is vaporization?

The change from a liquid to a gas is called vaporization.

100

what is sublimation?  

Sublimation occurs when the surface particles of a solid gain enough energy to form a gas.

100

what is boiling?

Boiling occurs when a liquid changes from a gas below its surface as well as at the surface.

200

what is melting and a melting point?

The change in state from a solid to a liquid is called melting.


In most pure substances, melting occurs at a specific temperature, called the melting point.

200

what is evaporation?

Vaporization that takes only on the surface of a liquid is called evaporation.

200

what happens during sublimation? 

 During sublimation, particles of a solid do not pass through the liquid state as they form a gas.

200

what is a boiling point?

The temperature in which a liquid boils is called its boiling point.

300

what happens to a substance during changes between solid and liquid? (part 1) 

At its melting point, the particles of a solid are vibrating so fast that they break free of their fixed positions.

300

what happens to a substance during changes between liquid and gas? (part 1) 

Condensation occurs when particles in a gas lose enough thermal energy to form a liquid.

300

what process occurs as dry ice gets smaller?

sublimation 

300

if a solid sublimates, then the gas condenses, what is the final form of matter?

liquid

400

what happens to a substance during changes between solid and liquid? (part 2) 

At its freezing temperature, the particles of a liquid are moving so slow that they begin to form fixed patterns.

400

what happens to a substance during changes between liquid and gas? (part 2)

Vaporization takes place when the particles in a liquid gain enough energy to form a gas.

400

what is the fog around dry ice?

water particles suspended in air.

400

what physical state is skipped during sublimation? 

liquid

500

You are stranded in the arctic, and dehydrated, what is better to do, melt ice, then drink, or just drink water?

melt ice then drink.

500

what is the opposite of vaporization? 

The opposite of vaporization is called condensation.

500

what is sublimation? 

Sublimation occurs when the surface particles of a solid gain enough energy to form a gas.

if a liquid evaporates, then the gas condenses, then the liquid freezes, what is the final state of matter?

solid
