Thermal Energy Flashcards
1
Q
What is a conductor?
A
A material that transfers heat energy quickly or easily.
2
Q
What is an insulator?
A
Something that prevents or slows down heat energy transfer.
3
Q
What is thermal energy?
A
The total energy of all the moving particles of an object. Faster moving particles means higher thermal energy.
4
Q
What is heat?
A
The transfer of thermal energy from one object to another.
5
Q
What is conduction?
A
When two objects make contact to transfer heat.
6
Q
What is convection?
A
Heat transfer caused by the rising and falling of hotter and cooler liquids or gases.
7
Q
What is radiation?
A
The transfer of thermal energy by invisible waves, through air or even empty space.
8
Q
What is thermal equilibrium?
A
When two objects in contact with each other reach the same temperature
