The following three objects (1) a metal tray, (2) a block of wood, and (3) a woolen cap are left in a closed room overnight. Next day the temperature of each is recorded as T₁, T₂ and T₃ respectively. The likely situation is

Options

  1. AT ₁= T ₂= T ₃
  2. BT ₃> T ₂> T ₁
  3. CT ₃= T ₂> T ₁
  4. DT ₃> T ₂= T ₁

Correct answer

A. T ₁= T ₂= T ₃

Step-by-step solution

All the three object will be in thermal equilibrium then % ~T ₁= T ₂= T ₃ .
