What are 8 types of energy stores?

Thermal
Kinetic
Magnetic
Chemical
Electrostatic
Elastic potential
Gravitational potential
Nuclear

What is the gravitational field strength on earth?

9.8 n/kg

define dissipated

energy that goes into the atmosphere

how do you draw a Sankey diagram?

draw a turn off for the wasted energy

define delocalised electrons

particles that are free to move and can move quickly

define Thermal conductivity

a measure of how quickly an object transfers energy by heating through conduction

how does conduction work?

electrons collide and vibrate

what is the difference between heat and temperature?

heat is the amount of particle and temperature is the degrees

define specific heat capacity

the energy needed by 1kg of a substance to increase its temperature by 1*c

what are the four steps to generating energy?

1. furnace
2. turbines
3. generator
4. national grid

what are 4 advantages of nuclear fuel

1. consistently reliable
2. 100,000 more rays than visible light
3. no co2
4.the safest fuel

what are 4 disadvantages to nuclear fuel

it needs to be cooled
