Christmas kecture Energy Extra

Question 1

Power

Answer 1

How fast energy is transferred

Question 2

Do electrons carry charge?

Answer 2

Yes

Question 3

Faraday Cage

Answer 3

(Named after Michael Faraday) it is an enclosure used to block electromagnetic fields

Question 4

Modern energy generators:

Answer 4

Wind power, microbial power, wee energy(converts bacteria to energy), foot (electromagnetic)

Question 5

How do big power stations generate electricity?

Answer 5

By splitting apart atoms

Question 6

What percentage of UK’s energy do fossil fuels account for?

Answer 6

50%

Question 7

How is electricity generated? (basic)

Answer 7

Energy gets converted into heat, heat into motion, motion into electricity

Question 8

What do fossil fuels release and contribute to?

Answer 8

Fossil fuels release carbon dioxide and contribute to global warming

Question 9

Energy (equation by Albert Einstein)

Answer 9

Energy=p = mass x speed of light squared
(E = mc squared)

Question 10

How do you get energy (hint: mentions atoms)

Answer 10

Atoms need to either get split or fused

Question 11

Hydrogen bomb

Answer 11

The most destructive weapon in the world

Question 12

Nuclear fusion

Answer 12

Have to get fuel extremely hot (10x centre of sun), this makes the fuel energetic causing charge particles (ions, electrons) to separate.

Question 13

Plasma

Answer 13

Fourth state of matter

Very energetic gas where ion and electrons have separated

Question 14

What can charged plasma be controlled by?

Answer 14

A magnetic field

Question 15

Where is a nuclear fusion reactor being built?

Answer 15

In the South of France

Question 16

Nuclear Fusion

Answer 16

Unlimited quantities of electricity

Small amount of carbon dioxide released

Question 17

Solar panels

Answer 17

Converts the suns energy into electricity

Question 18

What will next generation solar panels be made of and how would it help?

Answer 18

Copper, indium, gallium and selenium making it more flexible

Question 19

What is sunlight made up of

Answer 19

Made up of a spectrum of colours which have different energy levels, red has the least amount of energy

Question 20

Future planes

Answer 20

Plane powered by energy from the sun

Question 21

Is solar power likely to give us all the energy we will need in the future?

Answer 21

Solar power is unlikely to give us all the energy we need in the UK because of the limited land space and it is a challenge in Winter months, especially in Northern Europe.
