QuestionAnswer
What are the the properties of a liquid? The properties of a liquid are that it has a definite volume, but no definite shape.
How are the properties of a solid and gas different? The properties of gas are the complete opposite of the properties of a solid. Gas has no definite shape or no definite volume, while a solid has both definite shape and volume.
What type of energy is moving? Kinetic energy.
What is the result of force distributed over an area? Pressure.
What does absolute zero mean? Absolute zero is the temperature of 0K. Nobody has ever been able to produce a temperature of absolute zero.
Which law states that the volume of a gas is directly proportioned to its temperature in kelvins if the pressure and the number of particles of the gas are constant? The law is Charles's Law.
What is Boyle's Law? Boyle's Law states that the volume of a gas is inversely proportional to its pressure if the temperature and the number of particles are constant .
What is the reversible physical change that occurs when a substance changes from one state of matter to another. Phase change
How do endothermic and exothermic compare and contrast? Endothermic is when energy is absorbed, while exothermic is when energy is released.
What is heat of fusion? Heat of fusion is the energy required to change a gram of a substance from the solid to the liquid state without changing its temperature.
What is the phase change when a substance changes from a liquid to a gas? The phase change is called vaporization.
How is heat of vaporization similar to heat of fusion? They are both the energy required to create a phase change per gram without changing the temperature, but heat of vaporization is the conversion of liquid into a gas.
What is the process of evaporation? Evaporation is the process that changes a substance from a liquid to a gas below the substances boiling point.
What is the pressure exerted by water vapor in the atmosphere? Vapor pressure
What is condensation, and what is an example of it? Condensation is the process that changes a gas into a liquid. An example is dew.
What is the difference between sublimation and deposition? Sublimation is the phase change in which a solid transforms directly into a gas without passing through the liquid phase while deposition is when a gas transforms directly into a solid without passing through the liquid phase.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
