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

If you inflate a balloon at room temperature and then put it into a freezer. What will the balloon look like an hour later
What is the balloon would have shriveled up and deflated. This is because of the particles in the balloon slowed down due to the low temperatures in the freezer

What phase of matter has a definite volume but no definite shape
What is liquid
200
the phase change in which a gas changes to a liquid, it releases heat to its surroundings
What is condensation
200
the temperature at which a substance begins to change phases from a solid to a liquid
What is melting point
200
a mixture in which a solute is dissolved by a solvent, ex: sugar water and salt water
What is a solution
200
At sea level water boils at 100 degrees Celsius but on top of Mount Everest it boils at 71 degrees Celsius. Explain why.
What is since air pressure decreases with altitude so vapor pressure at which water boils also decreases
200

What is 20 cm cubed
300
the amount of mass in a given volume
What is density
300
a state of matter
What is a phase

What process lets you see your breath when the air is cold
What is vaporization
400
the phase change in which a gas becomes a solid, bypassing the liquid phase
What is deposition
400
a change in physical properties of a substance, such as mass, volume, density, or shape without changing the substance itself
What is a physical change
400
the phase change in which a solid becomes a gas, bypassing the liquid phase
What is sublimation
400
What is the density of a cube with sides of 4 cm and a mass of 512 g

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
500
In salt water, what is the solute and what is the solvent.
What is the solute is salt and the solvent is water
500
How is sublimation different than vaporization, condensation, and melting
