A pot on a stove gets hot due to this type of heat transfer.
What is conduction?
100
An example of this type of energy is a nuclear power station.
What is nuclear?
100
Power relies on these two factors.
What are work and time?
100
When energy is transferred, some of it is always "lost" as this.
What is heat?
100
This type of energy is shown by an owl flying.
What is kinetic?
200
Air currents heat up and cool off due to this type of heat transfer.
What is convection?
200
A toaster heats toast up. This is an example of what type of energy?
What is thermal?
200
Work relies on these two factors.
What are object moving in direction of the force?
200
Trace the transfer of energy from the gasoline to the car moving.
What is chemical --> mechanical?
200
This type of energy is shown by a ball sitting at the top of a hill.
What is potential?
300
You get a sunburn due to this type of heat transfer.

This type of energy occurs when a candle is lit.
What is light/radiant?
300
True or False: Jessica lifts a box. She is doing work on the box.
What is true?
300
A generator is used to turn on a light bulb. Trace the energy conversion.
What is mechanical --> electrical --> light?
300
Without changing the amount of work, the amount of power can be changed by doing this.
What is completing it in less time?
400
You stand near a fire. You get warm due to this type of energy transfer.

This is the Law of Conservation of Energy.
What is Energy cannot be created or destroyed, only changed in form?
500
Water boiling in a pan heats up due to this type of energy transfer.
What is convection?
500
This type of energy happens when work is done on an object.
What is mechanical?

Two students both do the same amount of work. Justin does it in 20 seconds and Zach does it in 15 seconds. This student has more power.
What is Zach?
500
Sarah pedaled her bicycle up a hill. Trace the energy involved, starting with the Sun.
What is chemical --> chemical --> mechanical?
500
A hot object is put in contact with a cold object. Describe what will happen to the two objects over the next 12 hours.
What is heat will transfer from the hot to the cold until they are the same temperature?
