THE IDEAL GAS EQUATION

pV = nRT

2

'p' in the Idel Gas Equation

pressure, Pa/Nm^-2

3

'V' in the Ideal gas Equation

volume, m^3

4

'n' in the Ideal Gas Equation

number of moles

5

'R' in the Ideal Gas Equation

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

6

'T' in the Ideal Gas Equation

temperature, K

7

Boyle's Law

Pressure increases when volume decreases (temperature is kept constant)

Pressure and volume of gas are inversely proportional

8

Charle's Law

Volume increases when temperature increases (pressure is kept constant)

Volume and temperature of gas are directly proportional

9

Pressure Law

Pressure increases when temperature increases (volume is kept constant)

Temperature is directly proportional to pressure

10
