What is Thermal energy?
The movement of particles/atoms
The movement of air
The flow of elements from one area to another
Thermal energy increases as (blank) increases
Give another name for Thermal energy
Thermal energy moves from
Cooler to warmer areas
Warmer to cooler areas
Lukewarm to freezing
Thermal energy continues to be transferred from one object to another until
One is hotter
One is colder
Both have the same temperature
They are lukewarm
The amount of thermal energy transferred from one object to another is dependent on
The difference in object width
The difference in object size
The difference in depth
The difference in temperature
When does the transfer of thermal energy occur?
When objects have the same temperatures
When objects have different temperatures
When one object is about to explode
When an object is overheated too much.
Conduction is the
Transfer of heat by direct contact
The flow of currents in a liquid or gas
Process of thermal energy transfer that occurs through space
The transfer of heat by particle collision
Conduction occurs easier in solids and liquids
Conductors don't conduct heat very well
Insulators don't conduct heat very well
Metals are good conductors
Fair conductors are all EXCEPT
Select the fair conductors below:

The transfer of heat by direct contact
Flow of currents in a liquid of gas
The process of thermal transfer that occurs through space
For a current to be formed, which air rises and which one sinks?
Cold air rises; warm air sinks
Warm air rises; cold air sinks
Select all examples of convection transfer
Heat travelling up a metal prong
Air in a room
Boiling water in a kettle
Heat from a candle
For heat transfer, radiation occurs through (blank) by electromagnetic waves
Radiation can occur in empty space AND solids, liquids and gases.
