What is Charles Law?
Charles Law Calculator: Charles Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant. This means that as temperature increases, volume increases, and vice versa.

How to Use the Charles Law Calculator
To use the Charles Law Calculator, enter the initial volume (V₁) and temperature (T₁) of the gas in the provided fields. Then input either the final volume (V₂) or final temperature (T₂). Click "Calculate" to see the results based on Charles Law: V₁/T₁ = V₂/T₂. The calculator will display the results in a table format.
Formula
V₁ / T₁ = V₂ / T₂
FAQs
1. What is Charles Law?
Charles Law describes the relationship between volume and temperature of a gas at constant pressure, stating that volume increases as temperature rises. It applies to ideal gases, allowing predictions of gas behavior under varying conditions.
2. How do I convert temperatures?
To convert temperatures, use these formulas: Celsius to Kelvin (K = °C + 273.15), Fahrenheit to Celsius (°C = (°F - 32) * 5/9). Always ensure temperatures are in Kelvin for calculations involving Charles Law.
3. Can Charles Law be used for all gases?
Charles Law is primarily applicable to ideal gases. Real gases deviate from ideal behavior at high pressures and low temperatures. However, it provides a good approximation for many gases under standard conditions.
4. What are the units of volume and temperature?
Volume can be measured in cubic meters (m³), liters (L), or milliliters (ml). Temperature should be measured in Kelvin (K) for calculations with Charles Law. Always ensure consistent units for accurate results.
5. What happens if I change the pressure?
If pressure changes, Charles Law no longer applies, as it assumes constant pressure. In such cases, consider the combined gas law or ideal gas law to relate volume, pressure, and temperature together appropriately.
