150 ~g of ice is mixed with 100 ~g of water at temperature 80^ C . The latent heat of ice is 80 cal / g and the specific heat of water is 1 cal / g - ^ C . Assuming no heat loss to the environment, the amount of ice which does not melt is -

Options

  1. A100 ~g
  2. B0 ~g
  3. C150 ~g
  4. D50 ~g

Correct answer

D. 50 ~g

Step-by-step solution

Heat loss by water = heat gain by ice. 100 1 80= m 80 m =100 gm ice melt Remaining ice =50 ~g
