Energy transfers
Energies
Kinetic
Energy of a moving object
Potential
Stored energy
Gravitational potential
Energy gained as height gained
Chemical potential
Energy that is released when chemical bonds are broken
Elastic potential
This could be the energy held in a spring or rubber band
Electrical potential
Voltage
Nuclear
When an atom is split there is a release of energy
Thermal
Heat
Wave
Energy transferred by waves
Radiation
Heat that moves in the form of waves
Different colours radiate heat at different rates
Travels through anything but glass
Black is best emitter and absorber
Shiny is best reflector
Convection
The particles are heated
They vibrate faster and move apart
This makes the liquid or gas less dense
This makes the volume increase
Thermal conduction
Conductors
Metal
How?
Thermal energy causes particles to vibrate more
Methods of heat transfer
State change
Sublimation
Deposition
Melting
Solidifying
Boiling
Condensing
Work = force x distance moved
