Solids, Liquids And Gases

Question 1

How does pressure change with depth?

Answer 1

It increases

Question 2

What is Brownian Motion?

Answer 2

The erratic, random movement of particles in a gas or fluid because of continuous bombardment from surrounding molecules

Question 3

What is the significance of Brownian Motion?

Answer 3

1. Explains why pressure acts in all directions
2. Explains why pressure of gases increases with temperature →more collisions with container and harder
3. The temperature in kelvin is proportional to the average KE of the gas molecules
4. Proves molecules exist

Question 4

What does Boyle’s law show?

Answer 4

That volume is inversely proportional to pressure

Question 5

What is the Boyle’s law calculation?

Answer 5

P1÷P2 = V1÷V2
