Question
For a system in thermal equilibrium, kinetic energy is shared equally among all of these things according to the equipartition theorem. For 10 points each:
[10h] Identify these things. A linear molecule of size N will have 3 translational, 2 rotational, and 3N minus 5 vibrational types of these things.
ANSWER: degrees of freedom [or DOF or modes]
[10e] The Gibbs phase rule states [read slowly] that the number of degrees of freedom of a system equals the number of components minus the number of phases plus this number. Helium has this atomic number.
ANSWER: two
[10m] For an ideal gas, an index described by this word equals [read slowly] f plus 2 over f, where f is the number of degrees of freedom. This word also describes processes with no net heat transfer.
ANSWER: adiabatic [accept adiabatic index]
