Energy Flashcards
The main facts about energy
- energy is never created or destroyed it is always stored or transferred
List the different types of energy sources
- Coal energy
- Nuclear energy
- Oil energy
- Solar energy
- Wind energy
- Wave energy
- Tidal energy
- Geothermal energy
- Hydroelectric energy
- Biomass energy
what are the different types of energy stores
- Thermal energy (heat energy)
- Kinetic energy
- Gravitational potential energy
- Elastic energy
- Chemical energy
- Magnetic energy
- Nuclear energy
- Electrical energy
what are the renewable energy sources ?
- Solar energy
- wind energy
- Geothermal energy
- Tidal energy
- Hydroelectric energy
- Biomass energy
- Wave energy
How is coal made ?
Coal is made from the remains of the trees
Overtime, the soil has pressure causing heat and then lignite is formed and then coal is formed
How is Oil and nuclear energy made ?
Nuclear and oil are made from the remains of the sea
- Dead sea marine and plants die and sink to the bottom of the sea
- then they are covered with mud
- Overtime more sediment is formed
- Causing pressure compressing the dead sea marine animals and plants to oil and nuclear
why are fossil fuel non-renewable ?
because they take a long time to form
What are the non-renewable energy ?
- Coal
- Nuclear
- Oil
When coal is burnt what energy transfer happens?
Chemical energy –> thermal energy
when water is heated and turned into steam what energy transfer happens ?
Thermal energy –> Kinetic energy
When steam pushes on the blades of the turbine and turns it around what energy transfer happens ?
Kinetic energy –> kinetic energy
A coil is turned inside a magnetic field and an electric current is produced what energy transfer happen ?
Kinetic energy –> electrical energy
where does conduction happens ?
through solids
