Ideal Gas Law:
| From: | To: |
The Ideal Gas Law is a fundamental equation in thermodynamics that describes the relationship between pressure, volume, temperature, and the number of moles of an ideal gas. It provides a mathematical model for predicting the behavior of gases under various conditions.
The calculator uses the Ideal Gas Law equation:
Where:
Explanation: The calculator automatically converts pressure from psi to Pascals (1 psi = 6894.76 Pa) before performing the calculation.
Details: Accurate volume calculation using the Ideal Gas Law is essential in various scientific and engineering applications, including chemical reactions, gas storage design, pneumatic systems, and environmental studies.
Tips: Enter the number of moles in mol, temperature in Kelvin, and pressure in psi. All values must be positive numbers. The calculator will automatically convert psi to Pascals and compute the volume in cubic meters.
Q1: Why convert psi to Pascals?
A: The Ideal Gas Law requires pressure in Pascals (SI units) for consistent calculation with other SI units (moles, Kelvin, and cubic meters).
Q2: What is an ideal gas?
A: An ideal gas is a theoretical gas that follows the Ideal Gas Law exactly, with particles that have no volume and experience no intermolecular forces.
Q3: When is the Ideal Gas Law most accurate?
A: The law is most accurate for gases at high temperatures and low pressures, where gas molecules are far apart and interactions are minimal.
Q4: What are the limitations of the Ideal Gas Law?
A: The law becomes less accurate at high pressures, low temperatures, and for gases with strong intermolecular forces or large molecular sizes.
Q5: How do I convert Celsius to Kelvin?
A: To convert Celsius to Kelvin, add 273.15 to the Celsius temperature (K = °C + 273.15).
