Ideal gas mixtures follow combined gas laws where total pressure equals the sum of partial pressures. This principle is vital in chemistry, meteorology, and engineering.
Fórmula
The calculator applies Dalton\'s law: P_total = P₁ + P₂ +

Exemplos resolvidos
Entrada
N₂: 79%, O₂: 21%, P_total = 1 atm
Resultado
P_N₂ = 0.79 atm, P_O₂ = 0.21 atm
Earth's atmosphere composition
Erros comuns a evitar
- ✕Multiplying partial pressures instead of adding them
- ✕Assuming all gases have identical properties
Perguntas frequentes
Does gas identity matter in partial pressure?
No, each gas independently contributes pressure. Gas molecules don't "know" what other gases are present.
How does humidity relate to gas mixtures?
Humidity is the partial pressure of water vapor relative to saturation; it's part of total atmospheric pressure.
