Equal volumes of water and alcohol when put in similar calorimeters take 100 sec and 74 sec respectively to cool from 500 to 400C. The thermal capacity of each calorimeter is numerically equal to the volume of either liquid. The specific gravity of alcohol is 0.8. If the specific heat capacity of water is 1 cal/g, the specific heat capacity of alcohol will be ?
A
0.6 cal/g0C
B
0.8 cal/g0C
C
1.6 cal/g0C
D
1.8 cal/g0C
Answer
0.6 cal/g0C
Explanation
Solution
2 gm ice at 00C is mixed with 5 gm steam at 1000C in a calorimeter of negligible heat capacity. At equilibrium the calorimeter will contain –
