Flashcards in ch 7 Deck (18):
1

pressure (p)

force exerted by gas paticles that hit the walls of container

2

atmospheric pressure(atm)

pressure exerted from gases from the air (O2 and N2)

3

as the altitude increases, the atm___

decreases

4

volvume (v) of gas is

equal to the size of container the gas is in

5

temperature (t)

related to kinetic energy

6

According to___law, Volume and pressure are ____proportional, if____are constant

Boyles, inversely
n and T are constant

7

According to___law, Volume and temperature are ____proportional, if____are constant

charles, directly
p and n are constant

8

According to___law, pressure and temperature are ____proportional, if____are constant

Hay lussac's
directly
v and n are constant

9

combined gas law

combination of charles, boyle and gay lussac's law

10

According to___law, Volume of gas and moles of gas are ____proportional, if____are constant

Avogadro's
directly
p and t are constant

11

molar volume

volume of 22.4 L occupied by 1 mole of a gas @ STP

12

ideal gas law

combines all 4 properties used in gas measurement

13

if a gas isn't at stp, what would you calculate and how?

calculate the moles of gas involved by using pressure.volume and temperature

14

partial pressure

pressure exerted if gas particle was the only type in container

15

dalton's law

total pressure= sum of partial pressures

16

kinetic molar theory of gases

1 small particles
2 attractive force=small
3. volume of gas=small
4. in constant motion
5. average kinetic energy=proportional to kelvin temperature

17

does atm change with weather and altitude?

yes

18

on a sunny day pressure is ____
on a rainy day pressure is ___

sunny=higher
rainy= lower
