17
Q

In which SOM is there a definite shape? [1]

A

Solid

18
Q

In which SOM is there a definite volume? [2]

A
  • Solid
    -Liquid
19
Q

Which SOM are NOT compressible? [2]

A
  • Solid
  • Liquid
20
Q

What happens when the physical process ‘MELTING’ happens? [2]

A

Forces between particles weaken, they’re no longer regularly arranged but still close, can move freely now

21
Q

What happens when the physical process ‘BOILING’ happens? [2]

A

Forces between particles weaken, particles become far apart

22
Q

What happens when the physical process ‘CONDENSATION’ happens? [2]

A

Forces between particles increase, particles become close together but can still move freely

23
Q

What happens when the physical process ‘FREEZING’ happens? [2]

A

Forces between particles increase, particles become fixed in position

24
Q

What are the fluid SOM? [2]

A
  • Liquid
  • Gas
25
Q

What are intermolecular forces? [1]

A

Forces that act between particles and hold them together. They get weaker when heated.

26
Q

What is DIFFUSION? [2]

A

The movement of particles from a region of higher concentration to a region of lower concentration, the particles are eventually evenly spread out.

27
Q

What is BROWNIAN MOTION? [1]

A

Random movement of particles

28
Q

What cause pressure in a gas? [1]

A

Particles colliding with the walls of the container.

29
Q

What happens to the volume and pressure if a gas is heated in a container which CAN expand? [2]

A
  • Volume increases
  • Pressure decreases
  • Because more there’s more space in the container which means it’s less likely to hit a wall.
30
Q

What happens to the volume and pressure if a gas is heated in a container which can NOT expand? [2]

A
  • Volume stays the same
    = Because it’s neither increasing or decreasing
  • Pressure increases
    = Because it’s getting heated which means more energy which means more particles colliding with walls.
31
Q

How does RELATIVE MOLECULAR MASS affect the rate of diffusion? [2]

A
  • When it’s higher = rate of diffusion is slower
  • When it’s lower = rate of diffusion is quicker
