Question

Some steam at $100^{o} C$ is passed into 1.1 kg of water contained in a calorimeter of water equivalent 0.02 kg at $15^{o} C$ so that the temperature of the calorimeter and its contents rises to $80^{o} C$ . Then the mass of steam condensed (in kg) is

Moderate

A

0.130
B

0.065
C

0.260
D

0.460

Solution

$m \times 540 + m \times 1 \times (100 - 80) = (1.1 + 0.02) \times 10^{3} \times 1 \times (80 - 15)$
$\Rightarrow m = 0.13 k g$
