Kinetic Energy
Kinetic energy is the energy of ________.
Motion
This tool is used to measure the average kinetic energy of molecules.
Thermometer
Conduction happens when two objects are in direct ________.
Touch/contact
Convection happens in these two states of matter.
Liquids & Gases
Radiation is the only type of heat transfer that can travel through this.
Vacuum
As molecules move faster, their kinetic energy does this.
Increases
This term refers to the total energy of all molecules in a substance.
Thermal Energy
This material is a great conductor often used in kitchens.
Metal
In a convection current, hot air does this because it is less dense.
Rises
The most famous example of radiation comes from this object.
The sun
This state of matter has the highest kinetic energy.
Gas
This is the unit used to measure Thermal Energy.
Joules
A material that slows down the transfer of heat is called this.
Insulator
In a convection current, cold air does this because it is more dense.
Sinks
You can feel this type of heat transfer without touching it, like standing near a ________.
Fire
This happens to the speed of molecules when you take thermal energy away.
Slow Down
If a cup and a swimming pool are the same temperature, this one has more thermal energy.
The pool
A metal spoon getting hot while sitting in a bowl of soup is an example of this.
Conduction
This "circle" of rising and sinking air or water is called a ________.
Convection Current
Name a type of wave to carry radiation energy.
Any electromagnetic wave.
True or False: Molecules in a solid ice cube have zero kinetic energy.
False (still vibrate)
Heat always moves from ________ to ________.
Hot to cold.
Why does a tile floor feel "colder" than a rug?
Better conductor so steals heat faster.
Why can’t convection happen in a solid rock?
Molecules too compact
Darker colors do this to radiation better than light colors.
Absorb
