Which type of heat transfer happens when you burn your hand on the stove?
conduction
3
The movement of thermal energy from a warmer object to a cooler object is called?
Heat
3
The average kinetic energy of the particles that make up a material.
temperature
3
Material through which heat flows easily?
conductors
3
Which type of heat transfer happens when you get a sunburn during a baseball game?
Radiation
5
Boiling water is what type of heat transfer?
Convection
5
Transfer of thermal energy between materials by direct collision of particles.
Conduction
5
What happens to the size of most materials when heated up? Why?
They expand and temperature goes up. This is because of thermal expansion.
5
Radiation is...
heat transfer through electromagnetic waves
5
If temperature increases, what happens to thermal energy?
It also increases.
8
You are supposed to get low toward the floor if you are ever caught in a building or house fire. The hotter air and smoke will rise and the cooler air will sink. What type of heat transfer does this represent?
Convection
8
True or False. Heat and thermal energy are the same thing.
False
8
Which has more thermal energy? A cup of hot chocolate or an Iceburg?
An Iceburg
8
Objects that do not transfer heat easily are called?
Insulators
8
What is a measure of the total value of the kinetic energy of a substance and the potential energy.
Thermal energy

Heat flows from
warmer to cooler temperature
10
Heat rising and cooling to form currents in a fluid is called?
convection, or a convection current

If temperature increases, kinetic energy of the particles _________________
Increases
12
When things heat up they sometimes increase in size (Like a metal bridge in the summer) What is this called?
Thermal expansion
12
Name something that does not have any thermal energy
Ha. Jokes on you. Every physical thing has thermal enegy
12
What is the vocabulary word that means "the amount of heat needed to raise the temperature of a substance 1 J/kg degrees C?"
Specific heat
12
Do ice cubes cool down the water? or does the water warm them up? Explain.
The ice cubes are warmed up by the water because heat only transfers from hot to cold.
12
If two objects are at the same temperature but have different masses, will they contain the same amount of thermal energy?
NO! More matter means more molecules of kinetic energy.
