Equation of state for ideal gases with Cobra3
Dependence of the pressure on the temperature under isochoric 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 general equation of state. For achange of state under isochoric conditions this equation becomes Amontons'law. In this experiment it is investigated whether Amontons' law is valid for a constant amount of gas (air).
