Thermal Energy

QuestionThe average kinetic energy of
Temperature The average kinetic energy of all particles in a substance
Kinetic Energy Energy in motion
Energy Transfer The movement of energy passed from one object to another
Conductor A substance that transfers thermal energy well (ex: metal)
Insulator A substance that does not transfer thermal energy well (ex: foam)
Convection Warm liquids and gases rise (less dense) and cold liquids and gases will sink (more dense)
Conduction The transfer of thermal energy through direct contact (touch)
Radiation The transfer of thermal energy through electromagnetic waves (ex: the sun)
Collide When two objects come into contact with each other
Particle A tiny unit of matter (this is what substances are composed of)
Stored Energy Energy that is saved for later use
Transfer The movement of energy from one place to another
Average The mean value of a set of numbers (sum of all numbers/how many numbers in the set)
Equilibrium When the two objects reach the same temperature or equal value
Ratio Comparison of two quantities (1:2)
Thermal Energy Total Kinetic energy of all particle in an object
Closed system System where matter and energy cannot enter or escape
Opened system System where matter and energy can enter or leave
Friction Force that opposes motion between two surfaces
Joule Unit of energy
Transformation of Energy Conversion of one from of energy to another
Thermometer Instrument used to measure temperature
Fahrenheit Temperature scale commonly used in the United States
Celsius Temperature scale commonly used in all other parts of the world
Law of Conservation of Energy Energy cannot be created or destroyed
Independent Variable The thing that you are testing in an experiment (one thing we can change)
Dependent Variable The thing we are measuring in an experiment
Controlled/Constant Variables All things other things that we must keep to same so the experiment/test is fair

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.
