The Ideal Gas Equation (Leaving Cert Chemistry): Flashcards

$PV = nRT$

Pressure in Pascals (Pa)

Volume in cubic metres (m³)

Amount of substance in moles (mol)

Temperature in Kelvin (K)

$8.31 \text{ J mol}^{-1} \text{K}^{-1}$

Boyle's Law, Charles' Law, Avogadro's Law

Volume inversely proportional to pressure (constant T)

Volume directly proportional to temperature (constant P)

Volume directly proportional to moles (constant T, P)

1000 L = 1 m³

$T(K) = T(°C) + 273$

22.4 litres or 0.0224 m³

0°C or 273 K
