A 11 kg block of ice at -15 °C is added to an insulated container partially filled with 12 kg of water at 20 °C.

Given: Cw = 4186 J/kg. °C; Cice = 2220 J/kg. °C, L= 3.34x10 J/kg

(a) Determine the final state of the mixture. Explain your answer.

Based on your answer in (a),

calculate either one (1) of the following: the mass of ice that melts. the final temperature of the system.

(c) Based on your answer in Q4(b), the system is then heated to 110°C. Assuming all water vaporizes, calculate the total energy of the system. Given: Ly = 2.26x100 J/kg, Csteam = 2.01x10' J/kg. °C

A 0.66300.6630 kg ice cube at −12.40−12.40 °C is placed inside a rigid, thermally isolated chamber containing steam at 365.0365.0 °C. Later, you notice that the ice cube has completely melted into a puddle of water. The specific heats of ice, water, and steam are ?ice=2093 J/(kg·∘C),cice=2093 J/(kg·∘C), ?water=4186 J/(kg·∘C),cwater=4186 J/(kg·∘C), and ?steam=2009 J/(kg·∘C),csteam=2009 J/(kg·∘C), respectively. If the chamber initially contained 6.1906.190 moles of steam (water) molecules before the ice was added, calculate the final temperature ?fTf of the puddle...

You have 1.60 kg of water at 27.0°C in an insulated container of negligible mass. You add 0.640 kg of ice that is initially at -22.6°C. Assume no heat is lost to the surroundings and the mixture eventually reaches thermal equilibrium. If all of the ice has melted, what is the final temperature (in °C, round to 2 decimal places) of the water in the container? Otherwise if some ice remains, what is the mass of ice (in kg, round...
