Question: the optimum drinking temperature for a shiraz is 150 c...

Question details

The optimum drinking temperature for a Shiraz is 15.0 ∘C . A certain bottle of Shiraz having a heat capacity of 3.40 kJ∘C−1 is 23.1 ∘C at room temperature. The heat of fusion of ice is 6.02 kJ mol−1 and the heat capacity of ice is 2.108 Jg−1∘C−1. Assume that no heat is lost to the rest of the surroundings.

What minimum mass of ice, originally at -6.0 ∘C , is required to bring the final temperature to 15.0 ∘C?
