1. What is Charles's Law?

Charles's Law states that the volume of an ideal gas is directly proportional to its absolute temperature when pressure is held constant. It's one of the fundamental gas laws in physics and chemistry.

2. How Does the Calculator Work?

The calculator uses Charles's Law equation:

Where:

• \( V \) — Volume of the gas (L)
• \( k \) — Proportionality constant (L/K)
• \( T \) — Absolute temperature (K)

Explanation: The law shows how gases tend to expand when heated, with the volume increasing linearly with temperature.

3. Importance of Charles's Law

Details: Understanding Charles's Law is crucial for predicting gas behavior in various applications including weather balloons, hot air balloons, and many industrial processes.

4. Using the Calculator

Tips: Enter the constant (k) in L/K and temperature in Kelvin. The calculator will compute the expected volume of the gas at that temperature.

5. Frequently Asked Questions (FAQ)

Q1: Why must temperature be in Kelvin?
A: Kelvin is an absolute temperature scale where 0 K represents absolute zero, making it appropriate for gas law calculations.

Q2: What are typical values for the constant k?
A: The constant depends on the specific gas and conditions. It's typically determined experimentally for a given system.

Q3: When does Charles's Law not apply?
A: The law is most accurate for ideal gases at low pressures and high temperatures. Real gases deviate at high pressures.

Q4: How does pressure affect this calculation?
A: Charles's Law assumes constant pressure. For changing pressure, the Combined Gas Law should be used.

Q5: Can I use Celsius temperature?
A: You must convert Celsius to Kelvin first (K = °C + 273.15) as the law requires absolute temperature.
