1. What is Boyle's Law?

Boyle's Law states that the pressure and volume of a gas have an inverse relationship when temperature is held constant. For a given amount of gas at constant temperature, the product of pressure and volume is constant.

2. How Does the Calculator Work?

The calculator uses Boyle's Law equation:

Where:

• \( P_1 \) — Initial pressure (Pa)
• \( V_1 \) — Initial volume (m³)
• \( P_2 \) — Final pressure (Pa)
• \( V_2 \) — Final volume (m³)

Explanation: The calculator solves for the missing variable when three of the four values are provided, maintaining the equality \( P_1 V_1 = P_2 V_2 \).

3. Importance of Boyle's Law

Details: Boyle's Law is fundamental in understanding gas behavior and has applications in various fields including respiratory physiology, scuba diving, chemical engineering, and meteorology.

4. Using the Calculator

Tips: Enter any three known values (leave one field empty). The calculator will compute the missing value. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units used in this calculator?
A: Pressure is in Pascals (Pa) and volume is in cubic meters (m³). You can convert from other units before entering values.

Q2: Does Boyle's Law apply to all gases?
A: Boyle's Law applies to ideal gases. Real gases follow this law approximately at moderate temperatures and pressures.

Q3: What assumptions does Boyle's Law make?
A: Boyle's Law assumes constant temperature and amount of gas, and that the gas behaves ideally.

Q4: Can I use different units?
A: Yes, but all pressure values must use the same units and all volume values must use the same units for the calculation to be valid.

Q5: What if I get an error or unexpected result?
A: Make sure you've entered exactly three values and left one field empty. Check that all values are positive numbers.
