At low temperatures, the Debye model leads to the result that the atomic heat capacity Cv for solids should be proportional to T3, and that for perfect crystalline solids it should become zero at absolute zero. Experimentally, the heat capacity is measured at temperature intervals to as low a temperature as possible.
At cold temperatures, the Debye model predicts that the atomic heat capacity Cv for solids should be proportional to T3, and for perfect crystalline solids it should become zero at absolute zero. Experimentally, the heat capacity is measured in temperature intervals down to as low a temperature as possible.
