2
Q
Describe the arrangement of liquids
A
Arranged randomly and held close
3
Q
Describe the arrangement of gases
A
No fixed arrangement, separate from each other
4
Q
Explain the effect of temperature on volume of a gas
A
As temperature increases the volume of a gas increases due to particles moving and colliding more quickly
5
Q
Explain the effect of pressure on volume of a gas
A
As pressure increases the volume of the gas decreases due to particles being held more closely
6
Q
What is diffusion
A
Mixing and moving of particles in liquids and gases
7
Q
How does the molecular mass affect the rate of diffusion
A
The higher the molecular mass of an element the slower the rate of diffusion (heavier or lighter particle)
