Final Volume (V₂) vs Initial Pressure (P₁)
Formula
## Combined Gas Law ### Formula **P₁V₁ / T₁ = P₂V₂ / T₂** Solving for V₂: **V₂ = (P₁V₁T₂) / (T₁P₂)** This combines Boyle's law (P ∝ 1/V), Charles's law (V ∝ T), and Gay-Lussac's law (P ∝ T) into one equation for a fixed amount of gas.
Esempio Risolto
A gas at 1 atm, 10 L, 300 K is compressed to 2 atm and heated to 350 K.
- 01V₂ = (P₁V₁T₂) / (T₁P₂)
- 02V₂ = (1 × 10 × 350) / (300 × 2)
- 03V₂ = 3500 / 600
- 04V₂ = 5.833 L
Domande Frequenti
What laws does the combined gas law combine?
It combines Boyle's law (constant T), Charles's law (constant P), and Gay-Lussac's law (constant V) into one equation.
Does it apply to real gases?
It works well for gases at moderate conditions. At high pressures or low temperatures, use the van der Waals equation.
Must temperature be in Kelvin?
Yes. Using Celsius will give incorrect results because gas laws require absolute temperature.
