Description

The experiment P1.7.3.3 measures the velocity of sound in the air as a function of the temperature ϑ and compares it with the linear function resulting from the temperature-dependency of pressure and density

The value c(0) determined using a best-fit straight line and the literature values p(0) and ρ(0) are used to determine the adiabatic coefficient κ of air according to the formula
