200 gm of a solid ball at 200C is dropped in an equal amount of water at 800C. The resulting temperature is 600C. This means specific heat of solid is -
A
One forth of water
B
One half of water
C
Twice of water
D
Four times of water
Answer
One half of water
Explanation
Solution
Heat absorbed by solid = Heat released by water
200 × Ssolid × 40 = 200 × Swater × 20
2 Ssolid = Swater
Ssolid = 2Swater
