16
Q

Boiling Point

A

temperature of a substance when changed from liquid to gaseous phase

17
Q

Deposition

A

process of the gaseous phase to the solid phase without passing the liquid phase

18
Q

Sublimation

A

process of the solid phase to the gaseous phase without passing the liquid phase

19
Q

Brownian Motion

A

Liquid and gas particle move randomly as they are bombarded by other particles in the fluid

20
Q

How does temperature affect Brownian motion?

A

The higher the temperature the faster the particles move around

21
Q

Diffusion

A

Movement of particles spreading

22
Q

How does temperature affect diffusion

A

When the temperature is cold the particles take more time to diffuse, and when the temperature is heated then the particles will diffuse faster as they get more kinetic energy

23
Q

How does size affect diffusion

A

Graham’s law; if the particles are heavy they will diffuse slower. Smaller molecules will diffuse faster than larger molecules due to the difference in their mass
