1) Calculate the average kinetic energy of the N2 molecules in a sample of N2 gas at 273 K and 546 K
2) Consider separate 1.0 L samples of He(g) and UF6(g), both at 1.00 atm and containing the same number of moles. What ratio of temperatures for the two samples would produce the same root mean square velocity?
Word document show how to calculate average kinetic energy and ratio of temperatures for two samples of a given element.
Kinetic Molecular Theory: Benzoic Acid
Benzoic acid, C6H5COOH, melts at 122 degrees C. The density in the liquid state at 130 degrees C is 1.08 g/cm^3. The density of solid benzoic acid at 15 degrees C is 1.266 g/cm^3.
In which state is the average distance between molecules the greatest?
Explain the difference in densities at the two temps in terms of the kinetic molecular theory.
