Calculate the rate of divacancy formation,(R_vv)=(Z₁)(Z₂)(C_v)(C_v)(v)(exp(-E_m/k_BT))in simple cubic and in bcc structure.

For a system with C_v independent of temperature, theheat added to a system at constant volume was seen to be Q =nC_vΔT. If Cv = constant*T² what is theequation for Q?

Explain why for solids and liquids the ratio of Cp and Cv (heat capacity at constant pressure and constant volume) is nearly one, while for a gas like nitrogen Cp/Cv = 1.4
