A student drops two metallic objects into a 120-g steel container holding 150 g of water at 25°C. One object is a 154-g cube of copper that is initially at 84°C, and the other is a chunk of aluminum that is initially at 5.0°C. To the surprise of the student, the water reaches a final temperature of 25°C, precisely where it started. What is the mass of the aluminum chunk?

(a) A student drops two metallic objects into a 120 g steel container holding 150 g of water at 25◦C. One object is a 200 g cube of copper that is initially at 85◦C, and the other is a chunk of aluminum that is initially at 5◦C. To the student’s surprise, the water reaches a final temperature of 25◦C, precisely where it started. What is the mass of the aluminum chunk? Specific heats of water, steel, copper, and aluminum are...

2.50 kg of water at 90 (degrees of C) is contained in a thermally-isolated container. A 1.50 kg chunk of ice at - 10 degrees C is added to the water, in the same thermally isolated container. a.) Describe the final state of the system when it has reached thermal equilibrium, give the final temperature and the amount of ice let (if any). b.) Find the net change in entropy of the system during this process.

42 * A piece of ice is placed in a container before it is filled to the brim with water. Once the water has been poured, the top of the piece of ice then exceeds the edge of the container. Does the container overflow when the ice melts? A. It depends on the amount of ice placed in the container at the start B. Yes, whatever time it takes for the ice to melt C. Not enough data to answer...

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...
