Chem Formulas & Gas Laws

What 4 things affect gas

temp, pressure, volume, amount

What does Boyles Law relate

Relates pressure and volume (indirect)

What does Charles Law relate

Relates volume and temperature (direct)

What does Gay-Lussacs Law relate

Relates pressure and temperature (direct)

What does Avogadro's Law relate

Relates volume and moles (direct)

Relates pressure, volume, and temperature (both direct and indirect)

Boyles Law Formula

P1V1=P2V2

Charles Law Formula

V1/T1=V2/T2

Gay-Lussacs Law Formula

P1/T1=P2/T2

Avogadro's Law Formular

V1/n1=V2/n2

Combined Gas Law Formula

P1V1/T1=P2V2/T2

Kinetic Molecular Theory (KMT)

1. gas particles are in constant and random motion

2. their collisions are perfectly elastic, there is NO LOSS of energy

3. the volume of an ideal gas is negligible, closed system// volume of gas so small

4. the average kinetic energy is expressed in the kelvin temperature (ºK)

Ideal Gas Constant (R)

0.08206 (L)(atm)/(mol)(K)

KMT Formula

PV=nRT

Density (D)

mass/volume

MM (mm)

mass/mol

mol (n)

mass/mm

atm

Pressure (P)

mols

Amount (n)

Kelvin

Temperature (T)

Liters

Volume (V)

Ideal Gas Constant

0.08206 Latm/molK
