Answer:

A calorimeter has mass 100 g and specific heat 0.1 kcal/ kg 0C. It contains 250 gm of liquid at 300C having specific heat of 0.4 kcal/kg 0C.

Explanation:

From the above question,

Heat gained by water and calorimeter = heat gained by the hot object.

Let the mass of each water, calorimeter and hot object be = m

Let the final temperature be = T

Thus,

Heat gain by water and calorimeter

= m×0.09×(T-30) + m×1×(T-30)  --- 1

Heat loss by the hot object

= m×0.09×(60-T)  --- 2

By equating (1) and (2), we will get,

= (T-30) ×1.09 = (60-T) ×0.09  .

On solving for T we will get  T = 32.3C

Therefore, the final temperature of water is 32.3°C
