シャルルの法則計算機

V₁/T₁ = V₂/T₂ を任意の未知数について解きます。

はじめに

Charles's Law Calculator — Solve V₁/T₁ = V₂/T₂ for any unknown. Enter V1 (L) — leave blank if unknown, T1 (K) — leave blank if unknown, V2 (L) — leave blank if unknown, T2 (K) — leave blank if unknown to get an instant, accurate result.

計算式

Charles's Law states that for a fixed amount of gas at constant pressure, volume is directly proportional to absolute temperature: V₁/T₁ = V₂/T₂, with temperature measured in Kelvin. Enter any three of the four values to solve for the fourth.

ステップごとの説明

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

実例

Example: With V1 (L) — leave blank if unknown = 2, T1 (K) — leave blank if unknown = 300, T2 (K) — leave blank if unknown = 350, the Charles's Law Calculator gives V1: 2, T1: 300, V2: 2.3333.

よくある質問

Who discovered Charles's Law?
Charles's Law is named after French scientist Jacques Charles, who found in the late 18th century that gas volume increases proportionally with absolute temperature at constant pressure.
Why must temperature be in Kelvin?
Charles's Law requires an absolute temperature scale because it describes a direct proportionality; Celsius or Fahrenheit include an arbitrary zero point that would make the ratio V/T meaningless or produce negative volumes.
What conditions must hold for Charles's Law to apply?
It assumes constant pressure and a fixed amount of an ideal gas, isolating the relationship between volume and temperature alone.
What inputs does the Charles's Law Calculator need?
You'll need to provide: V1 (L) — leave blank if unknown, T1 (K) — leave blank if unknown, V2 (L) — leave blank if unknown, T2 (K) — leave 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 Charles's Law Calculator?
The Charles's Law Calculator applies the formula exactly as calculated — Charles's Law states that for a fixed amount of gas at constant pressure, volume is directly proportional to absolute temperature: V₁/T₁ = V₂/T₂, with temperature measured in Kelvin. Enter any three of the four values to solve for the fourth. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Charles's Law Calculator free to use?
Yes, the Charles's Law Calculator is completely free, requires no signup, and runs instantly in your browser.

シャルルの法則計算機について

The Charles's Law Calculator uses a real, verifiable formula — Charles's Law states that for a fixed amount of gas at constant pressure, volume is directly proportional to absolute temperature: V₁/T₁ = V₂/T₂, with temperature measured in Kelvin. Enter any three of the four values to solve for the fourth. — so results are accurate every time, not an approximation.
