Thermal Properties of Matter

The quantities of heat required to raise the temperature of two solid copper spheres of radii r1r_1 and r2r_2 (r1=1.5 r2r_1 = 1.5\,r_2) through 1 K are in the ratio:

  1. A.278\dfrac{27}{8}✓
  2. B.94\dfrac{9}{4}
  3. C.32\dfrac{3}{2}
  4. D.53\dfrac{5}{3}

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