the temperature at which a substance begins to change phases from liquid to gas.
What is boiling point?
100
the amount of matter in something
What is mass?
100
the substance dissolved by a solvent to form a solution
What is solute?
100
the pressure exerted by a vapor.
What is vapor pressure?
100
It is vaporization
What is the process that lets you see your breath when the air is cold?
200
the phase change in which a gas changes to a liquid; condensation releases heat energy to the surroundings.
What is condensation?
200
the temperature at which a substance begins to change phases from solid to liquid
What is melting point?
200
the mixture in which a solute is dissolved by a solvent; e.g., a salt water and sugar water are solutions.
What is solution?
200
the phase change in which a liquid changes to a gas.
What is vaporization?
200

Lead has a density of 11.3 g/cm3. What volume of lead has a mass of 226 g?
300
the amount of mass in a given volume
What is density?
300
the 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
the substance that dissolves a solute to form a solution
What is solvent?
300
the amount of space an object or substance takes up
What is volume?
300
It is liquid
What phase of matter has a definite volume but no definite shape?
400
the phase change in which a gas becomes a solid, bypassing the liquid phase; the placement of sediment to produce land forms.
What is deposition?
400
change in physical properties of 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
It is because particles move at different speeds.
Why do you think temperature is measure of the "average" energy of motion of all the particles within a substance?
400
Sublimation generates its own energy.
How is sublimation different than vaporization,condensation, and melting?
500
the form of energy arising from the motion of all particles of in a system; heat energy moves between things that are at different temperatures; also called thermal energy
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 of the particles of matter in a substance.
What is temperature?
500
1,538 C
If 10 kg of iron melts at 1,538 C, at what temperature will 5 kg of iron melt?
500
.4 g/cm 3
Silver has a volume of 85 cubic centimeters and a mass of 212.5 grams. What is the density of the silver?
