- Explain Poisson's Ratio.The force constant for the internuclear force in a hydrogen molecule (H2) is k′ = 576 N /m. A hydrogen atom has mass 1.67 * 10-27 kg. Calculate the zero-point vibrational energy for H2 (that is, the vibrational energy the molecule has in the n = 0 ground vibrational level). How does this energy compare in magnitude with the H2 bond energy of -4.48 eV ?So, a "glass" with no or minimal crystal structure should be superconducting. If so, why?
