A mixture containing 21.4 g of ice (at exactly 0.00 ∘C) and 75.3 g of water (at 80.2 ∘C) is placed in an insulated container.

Assuming no loss of heat to the surroundings, what is the final temperature of the mixture?

Emery · Answer 1

Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. In a mixture it should be that heat gained is equal to the heat removed. We calculate as follows

Q1 = - Q2

21.4 (T2-0.00) = - 75.3 (T2 - 80.2)

T2 = 62.45
