Determination of density and coefficient of thermal expansion of a liquid at low temperature
Abstract
This paper presents the results of an experiment used to determine the density and coefficients of thermal expansion of two silicone oils in the temperature range of 25 C to -57 C. The experimental procedure is described, which is simple, yet accurate (approximately two percent error in the density) and can be constructed at low cost with readily available materials. The results are compared with manufacturer's data, and suggestions are made as to ways that the experiment could be modified to obtain better accuracy at a slightly higher cost.
