Transfer of energy through heat
Affecting factors of energy transfer
Energy transfers, efficiency and electrical energy
Generating and distributing electricity
Kinetic Theory
U-values measure how effective materials are as insulators
Solar panels- Heat water
Spesific heat capacity 1 KG- 1*C
Conduction, convection,evaporation and condensation
Temperature and colour of surfaces affects infrared radiation
Heat transfer depends on surface area, volume,material and type of surface
Convection- Heat in liquids and gasses
Conduction- Heat in solids
Electrical appliances carry out different energy transfers.
Amount of energy transferred depends on power and time used for
efficiency of a device which is useful= energy output/ total energy input
Energy is transferred or stored
Energy cant be created or destroyed
Heat from fuel and volcanic rocks changes water into steam
This spins turbines and generators
