A 2 kg copper block is heated to 500^ C and then it is placed on a large block of ice at 0^ C . If the specific heat capacity of copper is water is 3.5 10^5 ~J ^ - kg ⁻¹ , the amount of ice that can melt is

Options

  1. A7 8 ~kg
  2. B7 5 ~kg
  3. C8 7 ~kg
  4. D5 7 ~kg

Correct answer

C. 8 7 ~kg

Step-by-step solution

Heat emitted by copper = Heat gained by ice m c =m^ L m^ = m c L aligned & Given, m=2 ~kg , c=400 ~J ^ - kg ⁻¹ C ⁻¹ & =500, L=3.5 10^5 ~J - kg ⁻¹ & m^ = 2 400 500 3.5 10^5 = 8 7 ~kg aligned
