Webbheat capacity does not decrease with temperature as rapidly as suggested by Einstein's model because these long-wavelength modes are able to make a significant contribution to the heat capacity, even at very low temperatures. A more realistic model of lattice vibrations was developed by the Dutch physicist Webb(a) The degree of freedom is one. Reason: Diatomic gas molecule has at the maximum six degrees of freedom (2x3 = 6) out of which three are due to translational motion, two are due to rotational motion. (b) Monoatomic gas molecule has only three degrees of freedom and they are only translational. Diatomic gas molecule has five degrees of freedom.
