Question

A calorimeter contains 75 g of water at 15°C. When
50 g water of 100°C is poured in the calorimeter, the
temperature of the mixture becomes 25°C. Calculate
water equivalent of the calorimeter.​

Answer 1

Answer:

(m + 0.075)*1 *10 = (m+0.050)*1*75

10m + 0.750 = 75m + 3.750

65m = 3

m = 3/65 kg
