Chemistry Ch. 12 The Behavior Of Gases Section 2 Factors Affecting Gas Pressure

Front 1

by adding gas, you increase the number of gas particles, thus increasing

Back 1

the number of collisions, which explains why the gas pressure increases

Front 2

as long as the gas temperature does not change, doubling the number of gas particles

Back 2

doubles the pressure

Front 3

letting air out of a tire

Back 3

decreases the pressure inside the tire

Front 4

the fewer particles inside exert

Back 4

less pressure

Front 5

halving the number of gas particles in a given volume

Back 5

decreases the pressure by half

Front 6

when a sealed container of gas under pressure is opened, gas inside moves from the region of higher pressure to the region of

Back 6

lower pressure outside

Front 7

raising the pressure exerted by a contained gas by reducing its volume

Back 7

increases gas pressure

Front 8

the more the gas is compressed, the

Back 8

greater is the pressure it exerts inside the container

Front 9

reducing the volume of a contained gas by half

Back 9

doubles the pressure

Front 10

increasing the volume of the contained gas

Back 10

halves the pressure

Front 11

by doubling the volume, you halfve the gas pressure because

Back 11

the same number of gas particles occupy a volume twice the original size

Front 12

raising temperature of an enclosed gas can

Back 12

increase gas pressure

Front 13

the _____ and _____ of gas particles increase as the gas particles absorb thermal energy

Back 13

speed, kinetic energy

Front 14

the faster-moving paricles impact the walls of their container with more energy, exerting

Back 14

greater pressure

Front 15

if the average kinetic energy of a gas doubles, the Kelvin temperature

Back 15

doubles and the pressure of the enclosed gas also doubles

Front 16

a gas in a sealed container may thus generate _______ when heated

Back 16

enormous pressure

Front 17

as the temperature of an enclosed gas decreases, the particles

Back 17

move more slowly and have less kinetic energy

Front 18

halving the Kelvin temperature of a gas in a rigid container

Back 18

decreases the gas pressure by half
