Vocabulary
This is the measure of the average kinetic energy of particles
Temperature
When matter is heated, particles move faster or slower?
Faster
Heat transfer by touching
Conduction
The Sun warming your skin
Radiation
Heat always moves from *blank* to *blank*
Hot to Cold
Energy that flows from warmer objects to cooler objects.
Heat
When matter cools, particles move closer together or farther apart?
Move closer together
Heat transfer through empty space or waves
Radiation
Boiling water moving around in a pot
Convection
If particles are moving very fast, is the temperature is high or low?
High - they have more energy
A material that lets heat move through it easily
Conductor
Which state of matter has particles that vibrate in place?
Solid
Heat transfer caused by moving liquids or gases
Convection
Why do we use oven mitts
They are insulators that slow heat transfer - not a good material to transfer heat through
FOR DOUBLE POINTS: Name the phase change from liquid to gas
Evaporation or vaporization
A material that slows down heat transfer
Insulator
Which state of matter has particles that spread far apart and move freely?
Gas
A metal spoon getting hot in soup is an example of this
Conduction
Why does metal feel colder than wood at room temperature?
Metal conducts heat away from your hand faster
Food coloring spreads faster in hot water because particles move . . .
Faster
The energy of motion of particles
Kinetic energy
Explain what happens to particles during freezing
They lose energy, slow down, and move closer together
Warm air rises and cool air sinks. Name the type of heat transfer and explain why
Convection - warm air is less dense and rises
In the Ice Cream Lab, why did we add salt to the ice
To lower the freezing point and remove heat faster
Draw or describe particle spacing for a solid, liquid, and gas
