Question 8 A tank of water has been outdoors in cold weather, and a slab of ice 3.9 cm thick has formed on its surface (see the figure). The air above the ice is at 13°C. Calculate the rate of formation of ice (in centimeters per hour) on the ice slab. Take the thermal conductivity of ice to be 0.0040 cal/s cm-C°, its density to be 0.92 g/cm3, and its latent heat of fusion...

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....

2) A person pours 400 g of water at 45°C into an 855-g aluminum container with an initial temperature of 10°c. The specific heat of aluminum is 900 J/(kg-K) and that of water is 4190 J/(kg K). What is the final temperature of assuming no heat is exchanged with the surroundings? A) 3 B) 35°C D) 28°C E) 33°C 3) A heat engine with aneffic ency of 300% performs 300 of work. How much heat is discharged to the lower...
