25
What do the horizontal lines on the graph represent?
A change of state
26
What is diffusion?
The movement of particles from a high to low concentration
27
What three factors affect the rate of diffusion?
Temperature Particle Size The state of the substance that is diffusing
28
In which state does diffusion happen most quickly?
Gas
29
In which state does diffusion not happen?
Solid
30
How does temperature affect diffusion?
The higher the temperature, the faster the rate of diffusion.
31
How does particle size affect diffusion?
Smaller particles diffuse more quickly than larger particles.
32
Why does diffusion happen faster at higher temperatures?
The particles are moving faster
33
Why does diffusion happen faster in gases?
The particles are far apart. They travel a long way before colliding with another particle.
34
What equation links pressure, force and area.
Pressure = force / area
35
When you add gas particles to a container, what happens to the pressure inside?
It increases
36
What causes pressure inside a container?
Particles colliding with the walls of the container
37
What are the units for energy?
Joules (J)
38
What does the law of the conservation of energy state?
Energy cannot be created or destroyed.
39
What type of energy store is food and fuels?
Chemical energy store
40
Name the five main energy stores
1. Chemical 2. Thermal 3. Kinetic 4. Gravitational potential 5. Elastic potential
41
Describe the main energy transfer when a fuel burns
The chemical energy store decreases and The thermal energy store increases
42
What are the three main ways of transferring energy?
1. Electrical current 2. Light 3. Sound
43
What piece of equipment is used to measure temperature?
A thermometer
44
What are the units for temperature?
Degrees celsius (oC)
45
What happens to the energy transfer when an object is at equilibrium with its surroundings.
No more energy is transferred between the energy store of the object and its surroundings.
46
Which of the following does not involve particles? * Conduction * Convection * Radiation
Radiation does not involve particles
47
Name the energy transfer that occurs in solids
Conduction
48
Name the energy transfer that occurs in liquids and gases
Convection
49
Describe how energy is transferred by conduction
* Energy is transferred to particles * Particles vibrate _more_ * Particles _collide_ with neighbouring particles and energy is transferred
50
What is the name given to materials that are poor conductors?
Insulators
51
Give some examples of renewable energy resources
* Wind * Solar * Hydroelectric * Wave * Tidal * Geothermal * Biomass
52
What are the three fossil fuels?
Coal, oil and gas
53
Give examples of non-renewable energy sources
Nuclear and fossil fuels (coal, oil, gas)
54
What does renewable mean?
It will not run out
55
What pollutants can be released when fossil fuels burn?
Carbon dioxide Sulfur dioxide Solid particulates Nitrogen oxide
56
Name the gas that causes global warming
Carbon dioxide
57
What equation links power, energy transferred and time?
power = energy transferred / time
58
What are the units for power?
Watts (W)
59
What units are often used to measure energy usage in the home?
kilowatt hours (kWh)
60
What equation links work done, force and distance?
Work done = force x distance
61
What are the units for work done?
Joules (J) (because it's the same as energy transferred).
62
What are the units for force?
Newtons, N
