What is conduction?
The transfer of thermal energy through particles coming into contact with one another.
1 of 15
What medium does convection happen in?
Fluids.
2 of 15
What are light, shiny surfaces good at?
Reflecting radiation.
3 of 15
Radiation is transferred via what?
Waves.
4 of 15
How does evaporation cause cooling?
The liquid particles take heat energy from the surface, giving them energy to evaporate, leaving only cool particles behind.
5 of 15
What is a U-Value?
A measure of heat loss.
6 of 15
What is the formula for specific heat capacity?
Energy = mass x specific heat capacity x change in temperature
7 of 15
How are nuclear power stations powered?
Uranium rods are kept in water, when removed from the water they produce steam which turns a turbine.
8 of 15
Name the main advantage of nuclear power.
It does not produce greenhouse gases.
9 of 15
What does a step-up transformer do?
Increases the voltage of electricity.
10 of 15
What does the amplitude of a sound wave affect?
The volume.
11 of 15
When are waves diffracted the most?
When the size of the slit is equal to the wavelength.
12 of 15
Which electromagnetic wave has the smallest wavelength?
Gamma rays.
13 of 15
What is red-shift?
The shifting of light to the red side of the spectrum due to an increase in wavelength.
14 of 15
When a vehicle travels towards you, what is happening?
The pitch is increasing: the wavelength decreases, frequency increases.
