Heat
True or False: Heat/energy and thermal energy are the same.
False.
What are conductors?
Materials that allow heat/energy to pass through them.
Is there such thing as warm energy and cold energy?
No, there is just energy.
(Energy transfers, like warm things transfer their energy to cooler things)
The United States uses what type of temperature measurement?
Fahrenheit.
What does equilibrium mean?
A balanced state.
Heat flows from warm to cold or cold to warm?
Warm to cold.
What are insulators?
Materials that trap heat and do not allow energy to pass through them.
When energy increases in one part of the system it _______
increases in the other part
How can you find the temperature of an object?
You can add up the speed of the molecules and divide it by the number of molecule.
What is temperature?
The average kinetic energy.
How does Amplify measure energy/heat?
Celsius.
What are some examples of conductors?
Metals like copper, steel, and gold.
The transfer of energy between two objects stops when
both objects reach the same temperature (known as being stable, balanced, or at equilibrium)
How do you find the total thermal energy of an object?
You add up all the number of the speed of the molecules.
What is kinetic energy?
Energy that moves.
How do you measure thermal energy in Amplify?
Kilo-joules.
Why do people use insulators to keep things warm?
So no heat can escape the container and contents will stay warm.
When an object gets hotter, two things happen (pick two)
Molecules move faster
It has more kinetic energy
What is absolute zero?
The lowest possible temperature when molecules aren't moving.
What is stability?
When something stays the same over time.
Two different sized containers of water are boiling. Do they both have the same TOTAL KINETIC ENERGY?
No they do NOT. One container might hold more water than the other and hold more total kinetic energy.
What are some examples of insulators?
Foam and glass.
For things at the same temperature, the sample with more molecules has more total kinetic energy (thermal energy) than the sample with fewer molecules.
True
What is the formula for Fahrenheit to Celsius?
F = (9/5)C + 32.
What is potential energy?
Stored energy.
