A well-insulated, 64 fluid-ounce container is used for drinking water. Unfortunately, the water from the drinking fountain is about 75°F, a little too warm for average taste. To solve this problem, ice is added before filling it completely with water (volume of water and ice equals 64 fluid ounces). Calculate the precise amount of ice needed to cool the water to the coolest temperature that still provides optimal hydration (50°F) by the time all the ice melts and the temperature...

. A certain mass (m) of ice, initially at-5.00°C, is placed into a perfectly insulated container along with a certain mass (n) of steam (initially at 120°C). At equilibrium, there is only liquid water in the container. Write one completely detailed calorimetry equation necessary to solve for the equilibrium temperature of the water. Use symbols only (variables and constant names-no numbers), with all symbols defined (including Q's, AT's, etc.). You do not have to solve this equation or actually calculate...

(17%) Problem 6: You have mw = 4.9 kg of water in an insulated container. You add mı = 0.15 kg of ice at Ty=-19°C to the water and the mix reaches a final, equilibrium temperature of Tp = 11°C. The specific heats of ice and water are q = 2.10x10 J/(kg-ºC) and cw = 4.19x10 J/(kg:°C), respectively, and the latent heat of fusion for water is 4 = 3.34x10J/kg. Calculate the initial temperature of the water, in degrees Celsius....
