BJU Physical Sci 9

BJU Physical Science - Ch 9

QuestionAnswer
A theory that defined thermal energy as an substance that flowed from hot bodies into cold bodies. caloric theory
The flow of thermal energy from a hotter to a cooler object by direct contact. conduction
The flow of thermal energy from one place to another by the movement of particles. convection
The amount of thermal energy an entire object must gain or lose to change its temperature 1 °C. heat capacity
The absolute temperature scale, whose theoretical zero point is absolute zero. Its single fiducial point is the triple point of pure water (273.16 K); one kelvin is the same size unit as one degree Celsius. Kelvin scale
The amount of thermal energy absorbed per gram as a solid melts (fuses) at its melting point. The same amount of heat per gram must be released to freeze the substance. latent heat of fusion
The amount of thermal energy absorbed per gram as a liquid vaporizes. The same amount of heat per gram must be released to condense the vapor to a liquid. latent heat of vaporization
Nuclear particles or electromagnetic waves that radiate away from their sources; a method of heat transfer through radiant(electromagnetic) energy. radiation
The amount of thermal energy needed to raise or lower the temperature of 1g of a substance 1 C. specific heat
A temperature scale with fiducial points at the freezing point (0 °C) and the boiling point (100 °C) of pure water at 1 atm of pressure. Celsius scale
A temperature scale with fiducial points at the freezing point (32 °F) and the boiling point (212 °F) of pure water at 1 atm of pressure. Fahrenheit scale
Law stating that every natural process proceeds toward a condition of lowest usable energy and highest entropy. second law of thermodynamics
A quantity of thermal energy that flows from one system to another Heat
The measure of the average kinetic energy in a material Temperature
The study of thermal energy, heat, and their useful applications. Thermodynamics

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.
