100
This is when a solid turns into a liquid.
What is melting?
200
This temperature scale doesn't go below zero.
What is Kelvin?
200
Mechanical energy is this type of energy.
What is kinetic?
200
This is the temperature where all motion stops.
What is absolute zero?
200
This type of heat transfer occurs when warm liquids or gases rise and cool liquids or gases cool.
What is convection?
200
This is when a liquid turns into a gas.
What is evaporation?
300
This temperature scale has the freezing point of water at 0 degrees and the boiling point of water at 100 degrees.

This is when a gas turns into a liquid.
What is condensation?
400
This thing ALWAYS happens when you add heat to a system.

What is the concrete gets warm and will expand and crack if there are no spaces?
400
Name a device that transfers electrical energy into electromagnetic energy.
What is a microwave or an X-ray machine.... or other good answers! :)
400
This does not change during a phase change, even though heat is being added.
What is temperature?
500
Heat always moves in this direction.
What is hot to cold?
500
*TRICK QUESTION!* Name the energy transformations in a battery operated clock that has gears inside that makes it light up and works the alarm. (no using the word light)

500
This is why trash smells worse on a hot day as opposed to a cold day.
What is the molecules move faster and the smell diffuses through the air more quickly?
500
Fusion and fission are both types of this energy.
What is nuclear energy?
500
This is the temperature where water changes from a liquid to a gas. Answer is in K.
C = K + 273
