A material that is burned to produce thermal energy is ______.
fuel
sound

.
A series of vibrations that you can hear.
The ability to cause a change is ______.
energy
What properties of particles of matter do you measure with a thermometer?
The properties of particles measured by a thermometer are motion of energy.
________ is a measure of the average energy of motion of particles in matter.
Temperature
heat

.
The transfer of thermal energy from one piece of matter to another.
Thermal energy that travels from the sun to Earth is being transferred by ________.
radiation
compression

com pres sion
The part of a sound wave in which air is pushed together.
You put a pot of water on the burner of an electric stove and turn on the burner on high heat. The water soon boils. Describe how the heat from the stove gets to the water in the pot.
Heat from the stove transfers through conduction to the pot, which heats up, then conducts from the pot to the water.
thermal energy

ther mal en er gy
The energy of the motion of particles in matter.
A thermometer measures the ________ energy of motion of particles of matter.
average
Two pieces of the same kind of matter have the same temperature. The one with the larger mass has more ______.
thermal energy
A line graph has the temperature scale on the left and the time scale on the bottom. If the line is level, what can you conclude by interpreting the temperature data shown?
The graph indicates that the temperature remains the same over time.
________ is the transfer of thermal energy.
Heat
fuel

.
A material that can burn.
temperature

tem per a ture
A measure of the average energy of motion of the particles in matter.
energy

en er gy
The ability to cause a change.
________ is bundles of energy that can travel through empty space.
Radiation
_________ is the transfer of heat by particles bumping into each other.
Conduction
infrared radiation

in fra red ra di a tion
The bundles of light energy that transfer heat.
Suppose a thermometer is hanging from a thread inside a jar completely empty of gases or liquids. You infer that infrared radiation is falling on the thermometer. What observation would lead you to this inference? Explain.
The temperature on the thermometer is rising. It is rising because heat is transferring through infrared radiation from the sun to the matter within the thermometer causing it to expand and the temperature to rise.
Science
Heat Energy on the Move

.
solar energy

so lar en er gy
The energy given off by the sun.
Radiation that transfers heat is called ___________.
infrared radiation
Thermal energy can be transfered by conduction from one piece of matter to another only if the two pieces are __________.
touching
__________ is the heat transfer that can occur only in a liquid or gas.
Convection
radiation

ra di a tion
The bundles of energy that move through matter and through empty space.
The total energy of motion of particles of matter is _______.
thermal energy
convection

con vec tion
The transfer of thermal energy by particles of liquid or gas moving from one place to another.
Energy given off by the sun is called ________.
solar energy
Convection takes place only in liquids and ________.
gases
A solar panel on a roof collects solar energy to warm water for a house. Describe how the heat is transfered from the sun to the panel, and then from the panel to the water.
Heat is transferred from the sun to the panel through infrared radiation. The heat then transfers from the panel to the water through conduction.
conduction

con duc tion
The transfer of thermal energy caused by particles of matter bumping into each other.
pitch

.
A measure of how high or low a sound is.
sound wave

.
A moving pattern of high and low pressure that you can hear.
When thermal energy moves from one piece of matter to another, the transfer is called ________.
heat
Most thermometers work because matter _______ when it is heated.
expands
