Thermal Properties of Matter

The quantities of heat required to raise the temperature of two solid copper spheres of radii $r_{1}$ and $r_{2}$ ( $r_{1} = 1.5 r_{2}$ ) through 1 K are in the ratio:

A. $\frac{27}{8}$ ✓
B. $\frac{9}{4}$
C. $\frac{3}{2}$
D. $\frac{5}{3}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
