The Effect of Dissolved Air on the Density of Water

Abstract

An experiment to measure the change in density of water which has been saturated with air is described and the results given. The 80 points taken in the range 4°C to 20°C have been fitted to the equation Δρ = -4.612 + 0.106 t with density in 10-3 kg m-3 and t in °C, and confidence limits have been given. Other results are discussed.
