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 fixed 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 formula:

Where:

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

Explanation: The formula calculates the new volume of a gas when pressure changes, assuming constant temperature and amount of gas.

3. Importance of Boyle's Law

Details: Boyle's Law is fundamental in understanding gas behavior and has applications in respiratory physiology, scuba diving, syringes, and many industrial processes involving gases.

4. Using the Calculator

Tips: Enter all pressure values in Pascals (Pa) and volume in cubic meters (m³). All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What are the assumptions of Boyle's Law?
A: Boyle's Law assumes constant temperature, fixed amount of gas, and ideal gas behavior.

Q2: Can I use different pressure units?
A: Yes, but all pressure values must use the same unit, and all volume values must use the same unit for the calculation to be accurate.

Q3: What happens if temperature changes?
A: Boyle's Law only applies when temperature is constant. For changing temperatures, you would need to use the combined gas law or ideal gas law.

Q4: Are there real gases that don't follow Boyle's Law?
A: Yes, at high pressures or low temperatures, real gases may deviate from ideal behavior described by Boyle's Law.

Q5: What are some practical applications of Boyle's Law?
A: Breathing mechanics, syringe operation, carbonated beverages, and pressure regulators all rely on principles described by Boyle's Law.
