The specific heat of liquid mercury is 140 J/kgC. When 1 kg of solid mercury at its melting point of -39C is placed in a 0.5 kg aluminum calorimeter filled with 1.2 kg of water of temperature 20C, the mercury melts and the final temperature of the combination is 16.5 C. What is latent heat of mercury

In 1995 a research group led by eric cornell and carl wiemann at the university of colorado successfully cooled rubidium atoms to the 20-200 nk temperature range. assuming (incorrectly) that the rubidium atoms behave liké particles of a classical ideal gas, calculate the rms speed of a rubidium atom at a temperature of 112.0 nk. in the experiments one particular isotope of rubidium was used, rubidium-87. the molar mass of this isotope is 86.91 q/mol. tries 0/20 submit answer
