12/4 notes

Question 1

what is pressure

Answer 1

collision of gas molcules against the walls of the container

Question 2

what is volume

Answer 2

volume occupied by the gas (volume of the container)

Question 3

what is temperature

Answer 3

measure of the KE (also the speed) of gas molecules

Question 4

when does gas behave ideally

Answer 4

under low pressure and high temperature conditions

Question 5

when do gases behave nonideally

Answer 5

at high pressure and low temperature

Question 6

pressure if the molar mass is high

Answer 6

high pressure

Question 7

what is the SI unit for mass

Answer 7

kg

Question 8

look at notes for #molecules vs speed graph

Answer 8

ok

Question 9

diffusion

Answer 9

misxing of gas molecules by random motion when molecular collision occur

Question 10

effusion

Answer 10

escape of a gas through a pin hole into a vacuum without molecular collisiosn

Question 11

what are the assumptions in defining an ideal gas

Answer 11

-avg KE is proportional to tempertaure of smaple
-avg seperation between particle is greater than size of particle
-particles undergo collisions
