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
