Boyle's Law Formula:
| From: | To: |
Boyle's Law states that for a given mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. In the isothermal process, this relationship helps determine the gas constant which provides a correction for intermolecular forces and is characteristic of the individual gas.
The calculator uses the Boyle's Law formula:
Where:
Explanation: The equation calculates the gas constant by multiplying the pressure of compressible flow with the specific volume of the gas.
Details: Accurate calculation of gas constant is crucial for understanding gas behavior under different pressure conditions, designing pneumatic systems, and analyzing thermodynamic processes involving gases.
Tips: Enter pressure in Pascal, specific volume in m³/kg. All values must be valid (pressure > 0, specific volume > 0).
Q1: What is the significance of gas constant in thermodynamics?
A: The gas constant relates the energy scale to the temperature scale and is fundamental in the ideal gas law and various thermodynamic equations.
Q2: How does temperature affect Boyle's Law calculations?
A: Boyle's Law assumes constant temperature (isothermal process). Temperature changes would require different thermodynamic relationships.
Q3: What units should be used for accurate calculations?
A: For consistent results, use SI units: pressure in Pascal and specific volume in m³/kg to get gas constant in J/kg·K.
Q4: Can this calculator be used for real gases?
A: This calculator uses the basic Boyle's Law formula which is most accurate for ideal gases. For real gases, additional correction factors may be needed.
Q5: What are typical values for gas constants?
A: Gas constants vary by substance. For air, it's approximately 287 J/kg·K, while for other gases it can range from 200-520 J/kg·K.
