states of matter

Question 1

how do gasses cause pressure?

Answer 1

they collide with the walls of the container

Question 2

what will happen if you decrease the volume of a container of gas

Answer 2

pressure will increase due to an increase in collisions

Question 3

true or false. Volume is proportional to 1/pressure

Answer 3

True

Question 4

True or False. pressure is proportional to 1/volume

Answer 4

True

Question 5

True or Falce Pressure X Volume = constant K

Answer 5

True

Question 6

what is boils law?

Answer 6

Pressure1 X Volume1 = Pressure2 X Volume2

(only for Ideal gases)

Question 7

true or false. when a gas is heated it will increase in Ek

Answer 7

True

Question 8

at a constant temperature is pressure directly proportional to temperature?

Answer 8

Yes, but only when temperature is measured in Kelvin

Question 9

what are the assumptions of gas?

Answer 9

move very fast and randomly
has very little volume in comparison to volume between
no intermolecular forces
all collisions are perfectly elastic
tempriture is related to average Ek

Question 10

an ideal gas is a gas that follows kinetic theory of gasses. what do we call a gass that does not follow the kinetic thery?

Answer 10

a Real Gas

Question 11

what are some examples of Ideal gases?

Answer 11

N2, O2, Cl2, H2

Question 12

what is an Ideal gas?

Answer 12

a gas that obeys the ideal gas laws or has ideal gas behaviour

Question 13

what is a real gas?

Answer 13

gases that are close to ideal gas behaviour but deviate slightly

Question 14

under what conditions does a gas deviate from ideal gas behaviur

Answer 14

under high pressure
under low tempriture

Question 15

what is the ideal gas equation?

Answer 15

pV = nRT
where:
p = pressure (pa)
V = volume (m^3)
T = Tempriture (K)
n = Number of mols (mol)
R = the universal gas constant 8.314

Question 16

what is the universal gas constant/ proportionality constant?

Answer 16

8.314 Pa m^3 K^-1 mol^-1
