10 g of ice at -10^ C is mixed with 10 g of water at 0^ C . The amount of heat required to raise the temperature of mixture to 10^ C is

Options

  1. A400 cal
  2. B550 cal
  3. C1050 cal
  4. D1200 cal

Correct answer

C. 1050 cal

Step-by-step solution

Heat required for raising the temperature of water w = mw cw Tw =418.6 ~J , Similarly, heat required for raising the temperature of ice i =4381.2 ~J , thus the total heat in calorie will be roughly 1050 calorie.
