Force/Area

1kg * 1m/s^2

1N/1m^2

### standard temperature and pressure

STP = 1atm and 0 degrees celcius

### kinetic-molecular theory

gas particles are in constant rapid, random motion. Also particles of a gas are very far apart relative to their size

P1V1=P2V2

V1/T1=V2/T2

P1/T1=P2/T2

V=kn k=22.41

### ideal gas

a theoretical gas that follows all of these laws perfectly

PV=nRT

### diffusion

gases travel in all directions and mix quickly with molecules of gases in the air in a process.

### effusion

the passage of gas particles through a small opening

### Graham's law of diffusion

va/vb=Root(Mb/Ma)

### Gay-Lussac's law of combining volumes

if pressure and temperature are kept constant, gases react in volume proportions that are whole numbers

### Partial pressure

the pressure of each gas in a mixture

### Dalton's law of partial pressure

P(total)=P(a)+P(b)+P(c)

R=8.314LkPa/molK

1atm=760mm Hg

1bar= 101,325 Pa

### Millimeter of Mercury

1mm Hg= 133.322 Pa

### Pounds per Square inch

1 psi = 6.892 x 1000

1 torr = 133.322
