Determining the final temperature of a mixture of ice and water. Probably the most tedious calculations to make is the final temperature of a mixture. So let's give it a try and use your apparatus to validate your answer. In your calorimeter combine at least 400 g of water hotter than 70C with no more than 200 g of ice at a temperature of your choice. A data table is provided below to hold your data. Starting from

Q_{lost by water} = -Q_{gained by the ice and melt water} , write the full equation with all the individual terms. You should have four in all. Solve the equation for Tf showing all relevant steps. Substitute in all the data. Determine the theoretical value for Tf.
