As an approximate rule, a particular vibrational mode in a molecule will contribute to the equipartition principle energy at temperatures where 3 2 kBT Ú ve for that mode. In the following table are listed all the vibrational constants for several molecules. A sample of 1.00 mol of one of these molecules is heated from 350 K to 360 K, absorbing 698 J of energy in the process. Show which molecule is most likely the one in the sampleand degeneracies g = n, where n = 1,2,3, c . If the temperature is high enough that this becomes a roughly continuous (classical) distribution of states, write the integral you could use to calculate the average overall energy E in a sample of N molecules at temperature T.
Give two examples of applications where composites are used for non-structural applications.
Show that the spacing between (111) planes in the FCC structure is the same as the spacing (002) planes in the HCP structure. Imagine the atoms to behave as hard spheres.

One half of a mole of air is taken through the following processes in a closed piston-cylinder arrangement. From the initial state (V1 = 10 L, p1 = 1 atm) the gas is expanded at constant pressure to a volume of 20 L. It is then heated at constant vol..
The room air at 20oC that was trapped in the glass gets heated up to 40oC and some of it leaks out so the net resulting pressure inside is 2 kPa above ambient pressure of 101 kPa. Now the glass and the air inside cools down to room temperature, wh..
