Steam at 1000C is passed into 1.1 kg of water contained in a calorimeter of water equivalent 0.02 kg at 150C till the temperature of the calorimeter and its contents rises to 800C. The mass of the steam condensed in kg is –
A
0.130
B
0.065
C
0.260
D
0.135
Answer
0.130
Explanation
Solution
mL + m (100 – 80) = 1.1 × 1 × (80 – 15) + 0.02 × (80 – 15)
540 m + 20 m = 71.5 + 1.30
Ž m = 0.130
