12.2 ideal gas law

Question 1

recap what is KMT

Answer 1

1. gases are made of many small particles
2. particles are constant and are in random motion

Question 2

5 points of ideal gases

Answer 2

1. high translation energy
   move randomly in all direction
   move only in straight lines
2. when ideal gases entities collid w each other or on the walls, etc. the collisions are perfectly elastic (no loss of kinetic energy0
3. volumn of the ideal gas is insignificant (0)
4. there are no attraction or repulsion forces between ideal gas entities
5. gases do not condense into liquids when cooled.

Question 3

real gases… (2 points)

Answer 3

experience imfs and condense under conditions of high pressures, small volumn (which results in high densitty) and low temperature

@ high pressure there is a significant difference between volumne of gas and volumn of container

Question 4

ideal gas fails to repersent..

Answer 4

1) low temps
( particles move slower, more iMFs, slowed movement more time to react)
2. High pressures
( closer together, more IMfs)
3. high density particle
(high density = small volumn = more IMFs)
4. low volumn.

Question 5

ideal gases best present

Answer 5

1) high temps
- gas particles move therefore they are not affected by IMFs
2) low pressure
-> less interactions larger container volumn
