Heat

Project

QuestionAnswer
How does thermal energy work? It flows from a material at a higher temperature to a material at a lower temperature
What are thermal conductors? Metals, Aluminum, Copper, and Gold
What three ways can heat be transferred? Heat conduction,Convection, and thermal Radiation
What heats up quicker oil or water? Oil
What is Heat Conduction? It is the transfer of heat by the direct contact of particles of matter
What is the definition of Convection? Is the transfer of heat through the motion of fluids, such as air and water
What are thermal insulators? Foam, wood, and plastic
What is the definition of Radiation? Electromagnetic waves including light produced by objects because of their temperature
If You have a cup of hot coffee what will happen to the metal spoon? The heat from the coffee will move up the spoon using conduction
What happens if you turn on the heat in a cold room? The heat will circulate around the cold air and rise above pushing cooler air lower
If you put ice cubes in cold water on a warm desk what happens? The cup will condensate and the ice will slowly melt
Based on our investigation in lab, which has the lowest specific heat nails, flour, or water? Nails
What is specific heat? The amount of energy needed to change the temperature of a certain material
What does High specific heat do? Heat up or cool down slowly
What does Low specific heat do? Heat up or cool quickly
A substance has a specific heat of 2J/KG. How much energy is required to raise 10kg of the substance by 3 degrees? 60J
A 3kg object has a specific heat of 2J/gc. How much energy is needed to raise the temperature of the object by 3 degrees? 18J
24J of heat is applied to a 4kg object. If the temperature rises by 2 degrees, what is the specific heat of the object? 6J
What is the heat equation? E=mCp(T2-T1)
What does the heat equation tell you? The energy it takes to change the temperature of a mass of a substance with a specific heat value.

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.
