Answer 1

x 1000

Question 2

N/cm2 ➡ N/m2

Answer 2

x 10,000

Question 3

What direction does liquid pressure act?

Answer 3

Equally in all directions

Question 4

What is Brownian motion?

Answer 4

Random motion of particles due to collision with fast moving air particles

Question 5

What is Absolute Zero?

Answer 5

Temperature at which particles have no energy

-273 degrees centigrade = 0 K

Question 6

How do gases exert pressure on a container?

Answer 6

Bounce off walls at high speed
Change in velocity produce a force
Combined effect of forces acting over an area causes pressure

Question 7

What happens when you increase the temperature of a container?

Answer 7

Particles move faster
Hit wall harder
Pressure increases

Question 8

Boyle’s Law states that …

Answer 8

Pressure and volume are inversely proportional for a fixed mass of gas at a constant temperature

Question 9

Charles’ Law states that…

Answer 9

Volume is directly proportional to absolute (kelvin) temperature for a fixed mass of gas at a constant pressure

Question 10

Gay-Lussac’s Law states that…

Answer 10

Pressure is directly proportional to absolute (kelvin) temperature for a fixed mass of gas at a constant volume
