Mass of the calorimeter, m1
Answers
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
