what are the three way heat can be transferred?
radiation conduction and convection
what surface is best for absorbing heat?
what are the three states of matter and describe the formation?
solid,organised formation liquid,simarlar formation to solid but got some room to pass each other. gases,irregular formation and are free to move around
what is convection?
convection is where particle move towards a heat source
then they heat up and start to rise
as it moves away from the heat source it cool and start to sink
what is condensation ?
condensation is when gas turns to liquid
what is evapouration ?
evapouration is when liquid turns to gas
what animal have evolved small ears to minimize heat loss
the artic fox

what is the national grid
the national grid takes electrical energy from power stations to where it is needed across the country
what is the formula for waves
