The General Gas Equation (Grade 11 NSC Matric Physical Sciences): Flashcards

$\frac{p_1V_1}{T_1} = \frac{p_2V_2}{T_2}$

Kelvin (K)

$T(K) = T(°C) + 273$

Mass (or moles) must remain constant

$p \propto \frac{1}{V}$

$p \propto T$

$p \propto \frac{T}{V}$

Same units both sides (any units ok if consistent)

$\frac{pV}{T} = k$

All 3 variables (P, V, T) changing at once
