temperature & ideal gases

Question 1

what is Avogadro’s constant?

Answer 1

6.02 X 10^23

Question 2

What is molar gas constant?
[R]

Answer 2

8.31

Question 3

what is Boltzmann constant
[k]

Answer 3

1.38 x 10^-23

Question 4

what does Boyles’ law state?

Answer 4

p1v1 = p2v2
v is inversely proportional to p

Question 5

what does Charles’ Law state?

Answer 5

volume is directly proportional to temperature
(v1/t1)=(v2/t2)

Question 6

what is Gay-Lussac’s law?

Answer 6

(p1/t1) = (p2/t2)

Question 7

T/K is …

Answer 7

T/ celsius + 273.15

Question 8

Ideal gas obeys what formula

Answer 8

pV = nRT
pV = NkT

Question 9

What are the conditions of ideal gases?
3 components

Answer 9

Ideal gases:
1. exert no intermolecular forces on eo
2. move randomly and undergo perfectly elastic collisions w walls of container
3. occupy negligible fraction of volume of container

Question 10

when heat increases, what happens to intermolecular collisions of ideal gas and WHY?

Answer 10

when heat increase, no. of intermolecular collisions does NOT increase. Ideal gases do NOT have intermolecular forces of attraction

Question 11

why does evaporation have a cooling effect

Answer 11

particles that are more energetic & faster escapes the surface. particles left behind are less energetic thus mean KE of remaining particles reduced, thus drop in temp
