Ideal Gas Law Equation:
| From: | To: |
The ideal gas law (PV = nRT) describes the relationship between pressure, volume, temperature, and amount of an ideal gas. This calculator converts pressure in psi to volume in liters using the rearranged equation V = nRT/P.
The calculator uses the ideal gas law equation:
Where:
Explanation: The equation calculates the volume that a given amount of gas would occupy at specified temperature and pressure conditions, using appropriate unit conversions.
Details: Accurate volume calculation is crucial for gas storage, industrial processes, laboratory experiments, and engineering applications where pressure, temperature, and gas quantity relationships need to be determined.
Tips: Enter number of moles in mol, temperature in Kelvin, and pressure in psi. All values must be positive numbers greater than zero.
Q1: Why use this specific gas constant value?
A: The gas constant R = 1.2057 L·psi/(mol·K) is derived from the standard R = 0.082057 L·atm/(mol·K) converted using 1 atm = 14.6959 psi.
Q2: What temperature scale should be used?
A: Temperature must be in Kelvin (K). To convert from Celsius: K = °C + 273.15. From Fahrenheit: K = (°F + 459.67) × 5/9.
Q3: 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.
Q4: Are there limitations to this equation?
A: The ideal gas law becomes less accurate at high pressures, low temperatures, and for gases with significant molecular interactions.
Q5: Can this be used for real gases?
A: For more accurate results with real gases, modified equations like Van der Waals equation should be used, especially near condensation points.
