50 g ice at 0^ C in insulator vessel, 50 g water of 100^ C is mixed in it, then final temperature of the mixture is (neglect the heat loss)

Options

  1. A10^ C
  2. B0^ T_m 20^ C
  3. C20^ C
  4. Dabove 20^ C

Correct answer

A. 10^ C

Step-by-step solution

According to calorimeter principle, Heat given = Heat taken m₁ s₁(100-t)=mL+m₂ s₂(t-0) aligned 50 1(100-t) & =50 80+50 1(t-0) t & =10^ C aligned
