gas laws

boyles law

PV = PV

temp & amount of gas is constant

charles law

V/T = VT

• pressure and amount of gas is constant

gay - lussacs

P/T = P/T

• volume and amount of gas is constant

combined gas law

PV/ T = PV/T

• amount of gas must be constant

absolute zero

theoretical temp where where entites contain 0 kinetic energy

0K

KMT

idea that all supstances are composed of entities moving in a constant, random motion

translational motion

movement of entity in a linear path

rotational movement

spinning of entity in place, single bonds allow

vibrational

back and forth vibration of entites

stretching

KMT & states of motion

Solids : only vibrate ]

Liquids & gases : all 3

ideal gas

• imaginary standard to compare behvaiours of kniwn gases

• volume is insignificant

• elastic collisions, no loss of kinetic energy

• high translational enegry

what conditions will a gas behave most ideal in ?

high temp - more kinetic energy to have high translational energy

low pressure - allow volume of gas molecules to be negligible compared to empty space around them, too far apart to have IMF, keeping collisions elastic
