radiation conduction and convection

black matt

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

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

condensation is when gas turns to liquid

evapouration is when liquid turns to gas

wall insulation,loft insulation,hot water tank jaket,double glazing and draught-proofing

Energy transferred=mass*specific heat capacity*temparature

electric,light,sound,kinetic,nuclear,thermal,gravitational potential,elastic potential,chemical

false

light sound and heat energy

• efficiency=useful energy out
• useful energy in

energy =power x time

coal,oil,natural gas nuclear fuels

wind waves tides hydroelectric solar geothermal food biofuel

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

speed= frequency x wave length

radio micro infrared visible lights u.v x ray gamma rays
