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
