The phase change n which a gas changes to a liquid; condensation release heat energy to its surroundings.
What is condensation?
200
The temperature at which a substance begins to change phases from solid to liquid.
What is melting point?
200
A mixture in which a solute is dissolved by a solvent; e.g., salt water and sugar water are solutions.
What is solution?
200
A phase change in which a liquid changes to a gas.
What is vaporization?
200
What process lets you see your breath when the air is cold?
Condensation.
300
The amount of mass in a given volume.
What is density?
300
A state of matter; one of the different shapes of the moon as it progresses through a one-month cycle, as seen from the Earth.
What is phase?
300
A substance that dissolves a solute to form a solution.

300
The amount of space an object or substance takes up.
What is volume?
300
How is sublimation different from vaporization, condensation, and melting?
Sublimation does not include a liquid phase.
400
The phase change in which a gas becomes a solid, but bypassing the liquid phase; the placement of sediment to produce landforms.
What is deposition?
400
A change in physical properties in a substance, such as mass, volume, shape, or density without changing the substance itself.
What is physical change?
400
The phase change in which a solid becomes a gas, bypassing the liquid phase.
What is sublimation?
400
In salt water, which is the solute and which is the solvent?
Salt is the solute. Water is the solvent
400
Arlen added sugar to a glass of water. He stirs the water for 3 minutes. At the end of his stirring, a small amount of sugar remains at the bottom. No matter how much he stirs, he cannot get more of the sugar to dissolve. Suggest one way how Arlen could get the rest of the sugar to dissolve in water.
Heat the water up so it will evaporate.
500

What is heat energy?
500
The amount of a substance that will dissolve in a given amount of another substance
What is solubility?
500
The measurement of the average energy of motion (heat energy) of the particles of matter in a substance.
What is temperature?
