Angela claims that she wears a cylindrical-shaped hollow gold bracelet because it expands less than a solid one with a change in temperature. Clarissa claims that a cylindrical-shaped solid gold bracelet expands less than a hollow one. Which one, if either, is correct?
a. Angela, because the bracelet expands outward on its outer surface and inward on its inner surface. b. Clarissa, because the bracelet expands outward on its outer surface and inward on its inner surface. c. Angela, because the inner circumference does not change, but the outer circumference expands. d. Clarissa, because the inner circumference does not change, but the outer circumference expands. e. Neither, because both the inner and outer circumferences increase in length.
