Pressure is created by the gaseous particles hitting the inside walls of a container.
2 of 11
What happens to the particles when the temperature increases?
An increase in temperature means an increase in kinetic energy as the heat energy is converted into thermal energy.
Which means the particles collide more frequently with the container walls.
3 of 11
What will happen if a container's walls are flexible?
They will get bigger and bigger.
4 of 11
In terms of gas pressure, what does a decrease in volume mean?
Bigger gas pressure. This is because the collisions of gas molecules with the container walls are more frequent.
5 of 11
What is diffusion?
Is the process by which different liquids and gases mix due to the random motion of the particles.
6 of 11
How do diffusing particles move?
From an area of high concentration to an area of low concentration.
7 of 11
When is the concentration of the particles even?
When the particles are spread out to occupy all of the available space.
8 of 11
Does diffusion happen on it's own?
Yes, no input energy is required. Although it occurs faster at higher temperatures.
9 of 11
In which state does diffusion occur faster?
In gaseous particles because they move much quicker.
10 of 11
Do different gases diffuse at the same rate when the temperature is the same?
No, different gases do not diffuse at the same rate. This is due to the difference in relative molecular mass. Lighter particles can travel faster hence further. The lower the relative molecular mass the faster a gas will diffuse.
