pressure ( gas pressure)

Question 1

gas pressure is

Answer 1

the total force exerted by all the particles in the gas on a unit area of the container walls

Question 2

if the force per unit area of the particles decreases then gas pressure will ___

Answer 2

decrease

Question 3

increasing the temperature of a gas means that the particles will

Answer 3

move faster

Question 4

for a gas with a constant volume, if you increase the temp, then the force exerted on the container walls will also increase because (2)

2. what would happen to the gas pressure

Answer 4

• particles will collide more often with the walls of the container
• the particles will produce a larger force on the container

2. would increase

Question 5

if you decrease temperature, the particles move ____ and the pressure ____

Answer 5

slower, decreases

Question 6

at a constant temperature, decreasing volume would ____ pressure

Answer 6

increase

Question 7

decreasing the volume of a container would mean that

Answer 7

the gas particles have less room to move so the particles would collide with the container walls more often

Question 8

equation to find changes in volume and pressure at a constant temperature

Answer 8

pV= constant

P1V1=P2V2

( if you increase the volume, the particles will collide less often with the wall so the pressure would decrease)

Question 9

pressure in liquids acts _____ in all directions as long as ________

Answer 9

equally
as long as the liquid is not moving
