Calcolatore della legge combinata dei gas

Risolve la legge combinata dei gas P1V1/T1 = P2V2/T2 per qualsiasi variabile mancante.

Introduzione

Combined Gas Law Calculator — Solve the combined gas law P1V1/T1 = P2V2/T2 for any missing variable. Enter P1 (atm) — blank if unknown, V1 (L) — blank if unknown, T1 (K) — blank if unknown, P2 (atm) — blank if unknown, V2 (L) — blank if unknown, T2 (K) — blank if unknown to get an instant, accurate result.

Formula

Combined gas law: P₁V₁/T₁ = P₂V₂/T₂ (temperature in Kelvin). Enter any five of the six values to solve for the sixth.

Passo dopo passo

  1. Enter the P1 (atm) — blank if unknown.
  2. Enter the V1 (L) — blank if unknown.
  3. Enter the T1 (K) — blank if unknown.
  4. Enter the P2 (atm) — blank if unknown.
  5. Enter the V2 (L) — blank if unknown.
  6. Enter the T2 (K) — blank if unknown.
  7. Click Calculate to see your result instantly.

Esempio pratico

Example: With P1 (atm) — blank if unknown = 1, V1 (L) — blank if unknown = 10, T1 (K) — blank if unknown = 300, P2 (atm) — blank if unknown = 2, T2 (K) — blank if unknown = 300, the Combined Gas Law Calculator gives Unknown: v2, Value: 5.

Domande Frequenti

What does the combined gas law combine?
It merges Boyle's law (P₁V₁ = P₂V₂ at constant T), Charles's law (V₁/T₁ = V₂/T₂ at constant P), and Gay-Lussac's law (P₁/T₁ = P₂/T₂ at constant V) into one relationship for a fixed amount of gas.
Why must temperature be in Kelvin?
The gas laws are based on absolute temperature — using Celsius or Fahrenheit (which can be zero or negative at real conditions) would break the proportional relationship.
What inputs does the Combined Gas Law Calculator need?
You'll need to provide: P1 (atm) — blank if unknown, V1 (L) — blank if unknown, T1 (K) — blank if unknown, P2 (atm) — blank if unknown, V2 (L) — blank if unknown, T2 (K) — blank if unknown. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Combined Gas Law Calculator?
The Combined Gas Law Calculator applies the formula exactly as calculated — Combined gas law: P₁V₁/T₁ = P₂V₂/T₂ (temperature in Kelvin). Enter any five of the six values to solve for the sixth. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Combined Gas Law Calculator free to use?
Yes, the Combined Gas Law Calculator is completely free, requires no signup, and runs instantly in your browser.
