As temperature tends to zero, i.e. T arrow 0 K

Question

As temperature tends to zero, i.e. T arrow 0 K (A) specific heat of all substances approaches zero (B) specific heat of all substances approaches infinity (C) specific heat of all substances may be zero or infinity (D) None of the above

The prediction of specific heats, based on law of equipartition of energy, are independent of temperature. But as we go to low temperatures, there is a marked departure from this prediction. Specific heat of all substances approach zero as T arrow 0 K. This is related to the fact that degrees of freedom get frozen and ineffective at low temperatures.

Q. As temperature tends to zero, i.e. T→0K

specific heat of all substances approaches zero

specific heat of all substances approaches infinity

specific heat of all substances may be zero or infinity

None of the above
