A solid sphere and a hollow sphere are heated the same temperature. Point out the true statement.

Options

  1. Ahollow sphere cools more quickly.
  2. Bboth hollow and solid sphere cools equally.
  3. Csolid sphere cools more quickly.
  4. Dnone of the statement is true.

Correct answer

C. solid sphere cools more quickly.

Step-by-step solution

The solid sphere cools more quickly because the thermal conductivity of the solid sphere is more than that of the hollow sphere.
