A metal ball of mass 100 g at 20^ C is dropped in 200 ml of water at 80^ C . If the resultant temperature is 70^ C , then the ratio of specific heat of the metal to that of water is

Options

  1. A5 2
  2. B1 2
  3. C2 5
  4. D2 1

Correct answer

C. 2 5

Step-by-step solution

By principle of calorimetry Heat gained = Heat lost aligned & m ₁ ~s ₁ ( ~T - T ₁ )= m ₂ ~s ₂ ( ~T ₂- T ) & 100 s ₁ (70-20)=200 S ₂(80-70) & S ₁ ~S ₂ = 200 10 100 50 = 2 5 aligned
