Unformatted text preview: 1 A few more Light E electric field B magnetic field --in phase and 2 Equipartition of Energy The energy of a molecule is equally divided among all types of motion or degrees of freedom 3 For 1 mole of a diatomic gas: RT RT RT RT U 2 7 2 3 = + + = molar internal energy = translation + rotation + vibration It is easier to excite a molecule to a higher rotational level than to a higher vibrational or electronic energy level. The ratio of the population in any two energy levels E 2 and E 1 is given by the Boltzmann distribution law T k E B e N N = 1 2 The number of molecules in a state decreases with increasing energy of the state 4 Molar heat capactity: n C C V V / = and V V T U C = For 1 mole of monoaromic gas: 1 1 47 . 12 2 3 ) 2 3 ( = = = mol JK R T RT C V v For 1 mole of diatomic gas: 1 1 10 . 29 2 7 ) 2 7 ( = = = mol JK R T RT C V v 5...
