Problem 6.193

Can one consider the temperatures 20 and \(30 \mathrm{~K}\) as low for a crystal whose heat capacities at these temperatures are equal to \( 0.226 \) and \( 0.760 \mathrm{~J} / \mathrm{mol} \cdot \mathrm{K}) \)?

Reveal Answer
6.193 . Yes, because the heat capacity is proportional to \(T^{3}\) at these temperatures.
