Description: | Research Report Summary: Experiments were conducted on natural and artificial single ice crystals, commercial ice, snow-ice, and a glacial single crystal at temperatures from 0°C to -30°C to determine the effect of orientation on the linear thermal expansion coefficients. The orientation of the c-axis, the type of ice (whether single or polycrystalline), and the grain size did not appreciably affect the values of the coefficient; ice was practically isotropic with respect to thermal expansion at the temperatures tested. There was a steady decrease of the expansion coefficient with succeeding measurement on the same specimen, a phenomenon attributable to slow annealing. The ratio of the specific heat at constant pressure to that at constant volume 1.030 from 0°C to -30°C. Gruneisen’s constant was found to be about 0.78 and independent of temperature. An equation expressing the average coefficient of linear thermal expansion of ice of any type or orientation is presented. |
