THE IDEAL GAS EQUATION

pV = nRT

'p' in the Idel Gas Equation

pressure, Pa/Nm^-2

'V' in the Ideal gas Equation

volume, m^3

'n' in the Ideal Gas Equation

number of moles

'R' in the Ideal Gas Equation

gas constant - 8.314 J K^-1 mol^-1

'T' in the Ideal Gas Equation

temperature, K

Boyle's Law

Pressure increases when volume decreases (temperature is kept constant)

Pressure and volume of gas are inversely proportional

Charle's Law

Volume increases when temperature increases (pressure is kept constant)

Volume and temperature of gas are directly proportional

Pressure Law

Pressure increases when temperature increases (volume is kept constant)

Temperature is directly proportional to pressure

Pressure Conversion

atm to Pa ?

multiply by 101 325 Pa

Pressure Conversion

bar to Pa ?

multiply by 10^5 Pa

Temperature Conversion

from degree celsius to Kelvin ?

degree celsius + 273

Temperature Conversion

from Kelvin to degree celsius ?

K - 273

Volume Conversion

from dm^3 to m^3 ?

divide by 1000

Volume Conversion

from cm^3 to m^3 ?

divide by 1000000 m^3

Concentration of solution depends on

amount of solute and volume of solvent
