Science

TermDefinition
Temperature The measure of the average kinetic energy of the individual particles in an object
Three common scales Celsius, Fahrenheit, Kelvin
Fahrenheit scale The most commonly temperature scale used in the U.S.
Celsius scale Most commonly used scale
Kelvin scale Most commonly used scale for Physical science
Heat Is thermal energy moving from a warmer object to a cooler object
Specific heat A material with a high specific heat can absorb a great deal of thermal energy without a great change in temperature
Change in energy = Mass x Specific heat x Change in temperature
Heat is transferred by Conduction, convection, and radiation
Conduction heat is transferred from one particle of matter to another without the movement of matter itself
Convection Transfers heat within a fluid by the movement of currents
Radiation Is the transfer of energy by electromagnetic waves
If two objects have different temperature, Heat will flow from the warmer object to the colder one
Conductor A material that conducts heat well
Insulator A material that doesn't conduct heat well
States Solid, Liquid, and Gas
Change of State The physical change from one state of matter to another
Matter can change rom one state to another when Thermal energy is absorbed or released
Melting The change of state when a solid goes to a liquid
Freezing The change of state from a liquid to a solid
Evaporation If vaporization takes place at the surface of a liquid
Boiling Vaporization takes place at the bottom of a liquid
Condensation A change from the gas state to the liquid state
Thermal expansion The expanding of matter when it is heated
As the thermal energy of matter increases, Its particles spread out and the substance expands

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.
