What is mass?
What is the amount of matter in something.
100
What is boiling point?
What is the temperature at which a substance begins to change phases from a liquid to a gas.
100
What is a solute?
What is the substance dissolved by a solvent from by a solution.
100
What is physical change?
What is a change in physical properties of a substance without changing the substance itself.
100
What phase of matter has a definite volume but no definite shape?
What is the liquid phase?
200
What is volume?
What is the amount of space an object or substance takes up.
200
What is melting point?
What is the temperature at which a substance begins to change phases from a solid to a liquid.
200
What is a solvent?
What is the substance that dissolves a solute in a solution.
200
What is vapor pressure?
What is the pressure exerted by a vapor.
200
What process lets you see your breathe when the air is cold?
What is condensation?
300
What is density?
What is the amount of mass in an given volume.
300
What is condensation?
What is a phase change from which a gas changes to a liquid; condensation releases heat energy to it surroundings.
300
What is a solution?
What is a mixture in which a solute dissolves by a solvent.
300
What is vaporization?
What is the phase change in which a liquid changes to a gas.

A scientist wants to find the average energy of motion of the particles within a block of steel. What property is he trying to find?
What is temperature?
400
What is temperature?
What is the measurement of the average energy of motion of the particles of matter in a substance.
400
What is sublimation?
What is the phase change in which a solid becomes a gas by passing the liquid phase.
400
What is solubility?
What is the amount of a substance that will dissolve in a given amount for another substance.
400
Why do you think temperature is the measure of the "average" energy of motion of all the particles within a substance?
Temperature measures the "average" energy in motion of a particle because not all particles of a substance have the same energy in motion.

Estella investigated the properties of a grayish, shiny metal with a volume of 85 cm^3 and a mass of 212.5 g.
What is 2.5 g/cm^3
500
What is a phase?
What is the state of matter.
500
What is deposition?
What is a phase change in which a gas becomes a solid by passing a liquid phase.
500
What is heat energy?
What is the form of energy arising from the motion of all the particles in a system.

Suppose you inflate a balloon room temperature, but the balloon into a freezer, and come back an hour later. What will the balloon look like.
When the balloon is filled with gas, the gas moves rapidly. When it gets cold, it doesn't move as quickly. So the balloon deflates.
