liquid to solid/solid to liquid
what is freezing?
The change of state from liquid to solid is called freezing.
what is vaporization?
The change from a liquid to a gas is called vaporization.
what is sublimation?
Sublimation occurs when the surface particles of a solid gain enough energy to form a gas.
what is boiling?
Boiling occurs when a liquid changes from a gas below its surface as well as at the surface.
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.
what is evaporation?
Vaporization that takes only on the surface of a liquid is called evaporation.
what happens during sublimation?
During sublimation, particles of a solid do not pass through the liquid state as they form a gas.
what is a boiling point?
The temperature in which a liquid boils is called its boiling point.
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.
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.
what process occurs as dry ice gets smaller?
sublimation
if a solid sublimates, then the gas condenses, what is the final form of matter?
liquid
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.
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.
what is the fog around dry ice?
water particles suspended in air.
what physical state is skipped during sublimation?
liquid
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.
what is the opposite of vaporization?
The opposite of vaporization is called condensation.
what is sublimation?
Sublimation occurs when the surface particles of a solid gain enough energy to form a gas.
(FREE POINTS)
if a liquid evaporates, then the gas condenses, then the liquid freezes, what is the final state of matter?
solid
