10 g of ice at 00C is mixed with 100 g of water at 500 C. What is the resultant temperature of mixture?

A

31.20C

B

32.80C

C

36.70C

D

38.20C

Answer

38.20C

Explanation

Solution

Heat given by water = 100 × (50–q)

& heat taken by ice = 10 × 80 + 10 (q – 0)

̃ 100 × (50 – q) = 80 + 10 (q)

̃ q = 38.2 0C
