(21 cards)
biomass mean
The dry mass of energy in an organism.
chemical store mean
Energy that is stored in food, batteries or fuels.
conduction mean
The movement of heat through solids.
convection mean
The movement of heat through liquids and gases.
dissipated mean
Energy that spreads out into the environment.
elastic store mean
Energy that is stored when an object has changed
shape - for example, a spring or elastic band.
emit mean
To release or give out.
energy mean
There are many different types of energy - for
example, heat and light. The unit of energy is the
joule (J).
fossil fuels mean
Coal, oil and gas – these were formed from dead
animal and plants over millions of years.
gravitational potential mean
This type of energy is possessed by anything which
can fall.
infrared radiation mean
Radiation given off by the sun.
joule mean
The unit of energy; the symbol for it is J.
What is kilojoule
The symbol is KJ
1000J=1KJ
What is a kilowatts
The symbol is KW
1 KW= 1000W
kinetic energy mean
This type of energy relates to anything that
is moving.
nuclear energy mean
This is released from nuclear reactions.
radiation
The transfer of heat as a wave. Heat radiation is
affected by surface, colour and texture.
renewable mean
Energy sources that will not run out - for example,
solar or tidal energy.
temperature mean
How hot or cold something is, measured in 0C.
thermometer mean
A device that can be used to measure temperature.
watts mean
The unit of power – the symbol is W.
