gas laws 1

Question 1

boyles law

Answer 1

increasing pressure at constant temp, volume of gas decreases

(volume inversely r/t pressure)

Question 2

decreasing pressure with constant temp, volume

Answer 2

expands (Boyle’s Law)

Question 3

charles law

Answer 3

volume of ideal gas is proportional to its absolute temp under constant pressure

Question 4

gas ___ in volume when heated

Answer 4

expands

Question 5

if temp of a gas doubles, volume

Answer 5

doubles

Question 6

cuff volume increasing inETT is applying ___ law

Answer 6

charles

Question 7

gay lussacs law

Answer 7

pressure is directly proportional to temp if volume is constant

Question 8

temp goes up, pressure goes ___, if volume is constant

Answer 8

up

Question 9

gay lussacs tank example

Answer 9

as gas Is released, the liquid in tank vaporizes. heat is lost. temp in cylinder falls and pressure drops

Question 10

avogadro says

Answer 10

at equal temp and pressures, equal volumes of gas contian equal numbers of particles.

Question 11

the volume of gas is ___ proportional to the number of gas molecules as long as the temp and pressure are constant

Answer 11

directly (avogardros)

Question 12

at STP, one mole of a gas has a volume of

Answer 12

22.17 L

Question 13

avogadro’s number =

Answer 13

6.022 x 10^23

Question 14

ideal gas law

Answer 14

PV= nRT (n is moles and R is a constant)

Question 15

R describes the relationship between

Answer 15

temp and kinetic energy

Question 16

standard temp is

Answer 16

0*C or 273.17K

Question 17

partial pressure

Answer 17

pressure exerted by an individual gas in a mixture

Question 18

daltons law of partial pressures

Answer 18

states that the total
pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases:

PTotal = p1 +p2 + p3…

Question 19

if you’re giving a percentage of gas somewhere with an atm of 630 (Denver), they will get ___ gas

Answer 19

less

Question 20

calculate mole fraction

Answer 20

divide the number of moles of a gas by the total number of moles in a mixture

Question 21

relative humidity measures

Answer 21

the saturation of water in air.

Question 22

if there is a fixed amt of water in the air and the air temp decreases, how does the relative humidity change?

Answer 22

relative humidity will rise until it it reaches 100

Question 23

the temp at which moisture content in air will saturate the air is

Answer 23

dew point
