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

  • A
    hollow sphere cools more quickly.
  • B
    both hollow and solid sphere cools equally.
  • Correct answer
    C
    solid sphere cools more quickly.
  • D
    none of the statement is true.

Solution

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

Hence, the correct answer is option: 'C'.
