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 equation calculates the volume occupied by an ideal gas based on the number of moles, temperature, pressure, and the universal gas constant.
Details: Accurate volume calculation is crucial for various applications in chemistry, physics, and engineering, including gas storage design, chemical reactions, and thermodynamic analysis.
Tips: Enter the number of moles in mol, gas constant in J/mol·K (default is 8.314), temperature in Kelvin, and pressure in Pascals. All values must be positive.
Q1: 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 no intermolecular forces.
Q2: When is the ideal gas law applicable?
A: The ideal gas law works best for gases at high temperatures and low pressures where intermolecular forces are negligible.
Q3: What are the units for the gas constant?
A: The gas constant R is 8.314 J/mol·K, but it can be expressed in different units depending on the pressure and volume units used.
Q4: How does temperature affect gas volume?
A: According to the ideal gas law, volume is directly proportional to temperature when pressure and moles are constant (Charles' Law).
Q5: What are the limitations of the ideal gas law?
A: The ideal gas law becomes less accurate at high pressures and low temperatures, and for real gases with significant intermolecular forces.
