Aluminum-26 and Asteroid Heating. 26 Al was present when meteorites were forming (see PSRD article Using Aluminum-26 as a Clock for Early Solar System Events).It is a radioactive isotope with a half-life of only 700 thousand years, so its presence means that the solar system formed within a few half-lives of the formation of 26 Al in an exploding star. It decayed by emitting a …

Table of specific heat capacities

At elevated temperatures, and in an oxygen containing atmosphere, Fe oxides and chromite sand increase in weight. Because of this increase in weight during the LOI test, standard LOI testing cannot be run on chromite sand or chromite-silica mixtures. This change partially makes up for some of the weight loss because of the binder being burned off.

SPECIFIC HEAT CAPACITY OF SOILS AND MINERALS AS A

Aug 18, 2020· At 15°C, the precise value for the specific heat of water is 4.184 J K –1 g –1, and at other temperatures it varies from 4.178 to 4.218 J K –1 g –1. Note that the specific heat has units of g (not the base unit kg), and that since the Centigrade and kelvin scales have identical graduations, either o C or K may be used.
