Shortly after Ms. Berndt’s cat, Revere, was born, Ms. Berndt realized Revere wasn’t eating enough. She went to the pet store and bought many different kinds of food and fed Revere different types every day. Each day she noted the type of food and how much Revere ate out of his dish. Eventually Revere ate a lot of the Creppy Cat brand food and Ms. Berndt bought that for him from then on. Revere is the best worst cat ever.

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

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
