Question 1

How would you convert from celcius to Kelvin?

Answer 1

add 273

Question 2

How would you convert from Kelvin to celcius?

Answer 2

minus 273

Question 3

What is the relationship between volume and pressure?

Answer 3

Pressure is proportional to 1/volume
P times V is a constant

Question 4

Describe the effect of decreasing volume on pressure

Answer 4

As volume decreases, pressure increases
More frequent collisions between walls and particles as particles have less space
Same force exerted, over smaller area
P=f/a
p increases for smaller area and same force

Question 5

Describe the effect of increasing temperature on pressure

Answer 5

KE of particles increases
Move faster
More frequent collisions between walls and particles
More/harder force exerted on walls of container
P= f/a so increased force for given area means greater pressure

Question 6

Describe how a pressure is exerted on an area

Answer 6

Particles move in random directions, colliding with each other
Collisions between particles and walls of container
Force exerted on walls of container by particles
Pressure= force/area

Question 7

What is the relationship between temperature and pressure?

Answer 7

Pressure is proportional to Kelvin temperature
P/T is a constant
