Passage / Comprehension

A calorimeter of mass $m$ contains an equal mass of water in it. The temperature of the water and calorimeter is $t_{2}$ . A block of ice of mass $m$ and temperature $t_{3} < 0^{\circ} C$ is gently dropped into the calorimeter. Let $C_{1}$ , $C_{2}$ and $C_{3}$ be the specific heats of calorimeter, water and ice respectively and $L$ be the latent heat of ice.

Water equivalent of calorimeter is:

Options:

Answer:

Solution:

Water equivalent has the same heat capacity as the calorimeter.
$m C_{1} = W C_{2}$
$W = \frac{m C _{1}}{C _{2}}$
