unit c gasses

boyles law

as pressure increases, the volume of a gas decreases

temp + chem amount of a gas remain constant

boyles equation

P1V1=P2V2

charles law

as temperature increases, volume increases

charles equation

V1/T2=V2T1

gay l law

as pressure increases, temperature increase

gay l equation

P1T2=P2T1

combined gas law

combines three gas laws together that’s it

combined gas equation

P1V1T2=P2V2T1

ideal gas law

hypothetical gfas that obeys all gas laws ( GASES ARENT IDEAL )

we consider so we can solve problems

ideal gas equation

Pv=nRT

molar volume equation

n=V/Vm

avogadros theory

volumes of gas at same temperature and pressure contain equal numbers of molecules

absolute zero

lowest possible temp after which molecular motion stops

_____ consists of ___ particles

gases, tiny

why are the particles assumed to = 0

because of how small they are

particles are in…

constant random motion

with particles being with constant random motion, what happens in the container

particles collide with the walls which cause the pressure excerted by gas

do particles attract or repel eachother

neither they are neutral ( no repel or attract )

what of the gas particles is proportional to kelvin temp of gas

kinetic energy ( avg )

what have no mass

molecules of an ideal gas ( point masses )

molecules are…

point masses

graphs of what and what are perfectly straight lines

1. v and temp 2 pressure and temp

collisions are ____ and there are..

elastic, no intermolecular forces present

what is hypothetical and obeys all gas laws perfectly under all conditions

ideal gas
