Particle Theory
-
-
-
-
Conduction - Solids(no movement), particles, only in solids but not all
-
-
Convection - Liquids and gases(movement),particles, creates convection current
Convection Currents are formed when hot less dense air rises. Cold air rushes in to fill the gap. The hot air cools as it travels up and begins to sink. The process then reapets
-
Generating Electricity
-
Oil, Gas, Coal
Plants (coal) or animals(oil and gas) died 300,000,000 years ago. They are covered in silt and water which builds pressure. Deep Underground reaches 100 degrees and around the fossil fuels forms rock
-
The fuel is burned and heats water to produce steam. This then drives a turbine which turns a generates producing electricity
Nuclear Fission uses a neutron fired at a radioactive element which produces two lighter elements and two more neutrons plus energy
Solar
-
Solar PV
Absorbs energy and creates electricity, charging a battery.It can also heat water
Water
-
-
Dam
Water is slowly let out through the pennstock. The water rushes down which turns a turbine which turns a generator
Water is stored at the top. Water is slowly let out through the pennstock. The water rushes down which turns a turbine which turns a generator creating electricity. At night water is pumped back up at night
National Grid
-
-
-
A step up transformer turns a high current into high voltage to be transported across wires to minimise energy lost through heat
