PROBLEM 5-8 points You are making iced tea. The tea itself is initially at a temperature of 50.0 °C. You then toss in an ice cube with a mass of 50 and an initial temperature of -20.0 °C. The ice cube melts, and the final temperature of the mixture is +30.0 °C. For this problem, use the following values: c for liquid water is 4000 J/(kg "C), c for solid water is 2000 J/(kg°C), and the latent heat of fusion...

hello please
A 40-g block of ice is cooled to -78.0 degree C and then added to 560-g of water in an 80-g copper calorimeter at a temperature of 25.0 degree C. Determine the final temperature of the system consisting of the ice, water, and calorimeter (if not all the ice melts, determine how much ice is left). Remember that the ice must first warm to 0 degree C, melt and then continue warming as water. The specific heat of...
