-
what is condensation?
when a gas turns into a liquid
-
which wave from the EM spectrum has the highest frequency and energy?
Gamma rays
-
What is carbon capture?
carbon capture is to store and capture CO2 into empty fields. They do this to reduce the green house gas effect.
-
What is non renewable energy?
Energy that will run out eventually
-
Nmae a advantage of wind trubines?
Produce energy/no pollution/low running cost
-
Name all the renewable energys
Wind, waves, tides, hydroelectric, solar ,geothermal, food and biofuels
-
What does the national grid do?
The national grid takes electrical energy from power stations where it is needed in homes.
-
What is the equation to find out energy transfer?
Mass x specific heat capactiy x temperature change.
-
Name the nine types of energy?
electrical, light, sound, kinetic, nuclear, thermal, gravatational potential, elastic potential and chemical.
-
Can sound waves reflect and refract?
Yes
-
What is the amplitude of a wave?
The height of the wave measured from the rest point.
-
What is the equation to find out wave speed?
Frequency x wavelength
-
Why do artic foxes have small ears?
To minimise heat loss
-
What is evaparation?
When a liquid turns into a gas?
-
What three ways is heat transfered in?
Radiation conduction and convection
-
Name a disadvantage of wind turbines?
cost a lot to set up/ not reliable
-
Name the two types of waves?
longditudianl and transverse
-
What are U-values?
How fast heat can transfer
-
What are the three types of matter?
liquids solids and gases
-
Why are solids good at conducting?
Because of their free electrons
