Boyle's law (with Cobra4)
Correlation between volume and pressure under isothermic conditions.
Principle The state of a gas is determined by temperature, pressure and amount of substance. For the limiting case of ideal gases, these state variables are linked via the ideal gas law. In the case of isothermal process control this equation converts Boyle and Mariotte's law.
