friction

A force that builds up and creates heat when two objects rub against each other.

insulator

A material that does not easily transfer thermal energy or electric current between its particles ( rubber, wood, plastic).

conductor

A material that transfers energy easily;like metal.

thermometer

A tool to measure heat energy.

Why does conduction work very well in solid?

The molecules are compacted together enough to transfer the energy to another object.

Convection

Convection is the transfer of heat

fuel

Any material used to produce heat or power.

radiant energy (radiation)

Energy that travels in waves, like light, in all directions.

geothermal heat

Heat energy from inside Earth in the form of steam or hot water that is sometimes used to produce power

conduction

Heat is transfered by direct contact.

sea breeze

The flow of cooler air from over an ocean or lake toward land

heat energy

The flow of energy from a warm object to a cooler object.

wind

The movement of air from an area of high pressure to an area of lower pressure

Conduction

The process of heat transfer MOSTLY in a solid through direct contact.

absolute zero

The temperature at which all molecules stop motion, 0 degrees on Kelvin scale.

Celsius

The temperature scale on which water freezes at 0 degrees and boils at 100 degrees

Fahrenheit

The units of measure used to measure temperature in the customary (US) measurement system. Water Freezing 32 degrees and boiling 212 degrees

convection

Thermal energy is transferred by the movement of matter; this happens in gasses and liquids; WARM MATTER RISES AND COOLER MATTER SINKS; this makes gas and liquid flow in a pattern

transfer

To move something - heat moves to a place where the temperatures are cooler.

Heat flows FASTER when the objects in direct contact are of ____________ temperatures.

different

Heat will ONLY flow if the objects were of the __________temperature.

different

Temperature must be _____________ in order for heat to flow in the objects that are in direct contact.

different

How does heat flow between objects that are in direct contact? Does it flow from hot to cold or cold to hot?

hot to cold

Heat flows from hot to cold until it is the ________temperature in both objects that are in direct contact.

same

Heat will NOT flow if the objects were of the _____________ temperature.

same

energy

the ability to do work or produce heat

land breeze

the flow of air from land to a body of water

convection in our atmosphere

warm air rises cool air sinks

Heat energy flows from ________________________ materials

warmer to cooler
