Chem Unit 8: Gas Laws

General Properties of gases

fill up volume (expand)

free space

are uniform and mix in evenly in a container

What unit of tempeature is alwasy used

what does it specifcally represent

Kelvin is used because it can never be negative

it represents movement

units for pressure and conversons

1 atm = 101.3 kPa = 760 mmHg (torr)

how does a barometer work

presssure of the atmosphere pushes down on murucery pushing it up into the vaccum cube

gas properties list

V - volume

T- tempeture

n- moles

P- pressure

What happens if gas is added to a closed container?

What if its removed?

How is # of particles and pressure coorilatated if other factors are the same.

Adding will increase the pressure because more particles will collide more, creating more pressure

less particles will reduce pressure because less particles will crash into each other

they are directly coorilated, so if moles are doubles, pressure will double

What happens if there is too much pressure in a container

it can explode, like a balloon

Gas Equillibrum

gas pressure will want to even out from inside and outside
particles move from high to low

What happens if size of container is changed?

How is it coorilated.
