A block of mass 2 kg is kept at temperature 2000C is put into a calorimeter of water equivalent 40 gm contain 960 gm of water at 400C. The resulting temperature of mixture is (Sp. heat of block = 0.1 Cal/gm-0C)
A
66.67 0C
B
56.36 0C
C
76.3 0C
D
60.1 0C
Answer
66.67 0C
Explanation
Solution
1000 × 1 (T –40) = 2 × 1000 × 0.1 (200 – T)
T = 66.670C
