Conduction, convection, Heat Energy
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
