Calculateur de la Loi de Charles
Calculez le volume ou la température d'un gaz à pression constante avec la loi de Charles.
Final Volume
20.0000 L
Final Volume vs Initial Volume
Formule
Charles's Law
At constant pressure, the volume of a gas is directly proportional to its absolute temperature.
Formula
V1 / T1 = V2 / T2
Temperature must be in Kelvin. Heating a gas causes it to expand.
Exemple Résolu
10 L of gas at 300 K heated to 600 K at constant pressure.
- 01V1/T1 = V2/T2
- 02V2 = V1 * T2 / T1
- 03V2 = 10 * 600 / 300
- 04V2 = 20 L
Questions Fréquentes
Why must temperature be in Kelvin?
The Kelvin scale starts at absolute zero, where gas volume would theoretically be zero. Using Celsius would give incorrect ratios because 0°C is not zero temperature.
How do hot air balloons work?
By Charles's law, heating the air inside the balloon increases its volume (and decreases its density), creating buoyancy.
Who was Jacques Charles?
A French physicist (1746-1823) who first described the volume-temperature relationship of gases in 1787.
