QuestionAnswer
what is the definition of temperature? temperature is a measure of how hot(or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object
What is the definition of thermometer? A thermometer is an instrument that measures and indicates temperature
What is the definition of heat? Heat is the energy transferred between objects that are at different temperatures
What is the definition of absolute zero? Absolute zero is the temperature at which molecular energy is at a minimum( 0 K the Kelvin scale or -273.15 degrees Celsius on the Celsius scale)
what is the definition of thermal conduction? Thermal conduction is the transfer of energy as heat through a material
What is the definition of convection? Convection is the movement of matter due to differences in density that are caused by temperature variations
What is the definition of convection current? Convection current is any movement of matter that results from differences in density; may be vertical, circular, or cyclical
What is the definition of radiation? Radiation is the energy that is transferred as electromagnetic waves, such as visible light and infrared waves
What is the definition of specific heat?? Specific heat is the quantity of heat required to raise a unit mass of homogenous material 1K or 1 degree Celsius in a specified way given constant pressure and volume
What is the definition of entropy? Entropy is a measure of the randomness or disorder of a system
What is the definition of a heat engine? A heat engine is a machine that transforms heat into mechanical energy, or work
What kind of things do people take temperature readings on? People take temperature readings on air outside to decide what to wear, to find out if you are ill, and if the turkey is done or not
what is being measured when you are taking temperature readings? When you are taking temperature readings you are measuring the kinetic energy
What is the temperature of a substance proportional to? The temperature of a substance is proportional to the average kinetic energy of the substance's particles
what are many decisions made based on? Many decisions are made based on temperature
What do all particles have? All particles have kinetic energy
What are all particles in a substance doing? All particles in a substance are constantly moving
What do each of the particles have because they are moving? Each particle has kinetic energy because they are moving
What is temperature related to? Temperature is related to the kinetic energy of particles
What happens when the average kinetic energy of the particles in an object increase? When the average kinetic energy of the particles in an object increases, the object's temperature increases
example of this the particles in a hot car hood move faster than particles in a cool car hood because the hot particles have more kinetic energy
is it possible to find the kinetic energy of every particle in an object? It is impossible to find the kinetic energy of every particle in an object and calculate their average energy
What do most substances do when their temperature increases? Most substances expand when their temperature increases

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.
