A person makes a quantity of iced tea by mixing 260 g of hot tea (essentially water) with an equal mass of ice at its melting point. Assume the mixture has negligible energy exchanges with its environment. (a) If the tea's initial temperature is Ti = 91°C, when thermal equilibrium is reached what are the mixture's temperature Tf and (b) the remaining mass mf of ice? If Ti = 62°C, when thermal equilibrium is reached what are (c) Tf and...

Chapter 18, Problem 035 An insulated Thermos contains 150 cm3 of hot coffee at 86.0°c. You put in a 18.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg K. The latent heat of fusion is 333...

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...

An insulated Thermos contains 170 cm3 of hot coffee at 82.0°C. You put in a 13.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg. The density of water...

6. (2 points) You are given 400 g of coffee (same specific heat as water) at 95.0°C (too hot to SS drink). How much ice (at 0.0°C) must be added to your coffee in order to cool it to 50.0°C? Neglect heat content of the cup and heat exchanges with the surroundings. Latent heat of fusion of ice is 3.33x10 J/kg: Specific heat of ice is 2100 J/(kgx°C). You must know the specific heat of water....
