Question

Consider a balloon of nitrogen gas and a crystal of sugar sitting on a table at room conditions. Select the appropriate statement to fill in the blanks of each of the following. Note that there are only two parts but four questions. You must get both questions correct in a part to get credit for that part.

First part - comparing the same energy in different molecules

a) The thermal energy of the sugar molecules is ______ that of the nitrogen molecules.

greater than,about the same as,less than

b) The energy of interaction between sugar molecules is _____ that of the nitrogen molecules.greater thanabout the same asless than

Second part - comparing different energies in the same molecule
