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 pressure exerted by an ideal gas based on the number of gas particles, temperature, and volume of the container.
Details: Accurate pressure calculation is crucial for various applications including chemical engineering, atmospheric studies, industrial processes, and scientific research involving gas behavior.
Tips: Enter number of moles in mol, temperature in Kelvin, and volume in cubic meters. All values must be positive numbers greater than zero.
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 not accurate?
A: The law becomes less accurate at high pressures, low temperatures, and for gases with strong intermolecular forces or large molecular sizes.
Q3: Why use Kelvin for temperature?
A: Kelvin is an absolute temperature scale where 0 K represents absolute zero, making it appropriate for gas law calculations.
Q4: What are common units for pressure?
A: While this calculator uses Pascals (Pa), pressure can also be measured in atmospheres (atm), mmHg, torr, or bar, with appropriate conversion factors.
Q5: Can this calculator handle real gases?
A: This calculator uses the ideal gas law, which works best for ideal gases. For real gases under extreme conditions, more complex equations like Van der Waals equation should be used.
