TermDefinition
conduction Movement of electric charge or thermal energy through an object or from object to object through direct contact.
convection Movement of thermal energy as fluids move.
first law of thermodynamics The law that states that energy cannot be created or destroyed but only transferred between objects or transformed; also known as the law of conservation of energy.
heat Movement of thermal energy from an area of higher temperature to one of lower temperature.
radiation Movement of energy in the form of electromagnetic waves.
second law of thermodynamics The law that states that energy can flow from a colder object to a warmer object only if something does work.
specific heat The energy required to raise the temperature of 1 g of a substance 1 degree C.
temperature (T) The measure of the hotness or coldness of a substance; proportional to the average kinetic energy of the particles within the substance.
thermal conductor A material through which thermal energy moves easily.
thermal energy The sum of the kinetic energies of all the particles within an object.
thermal insulator A material through which thermal energy does not easily move.
thermodynamics The study of thermal energy and heat and how they relate to work and other forms of energy.
thermometric property Any property that changes predictably with changes in temperature.
third law of thermodynamics The law that states that entropy would be at its minimum value at absolute zero. Therefore, absolute zero can never be achieved.

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.
