- A cup of water at Temperature of 21 degrees Celsius with .5 [kg] of water is sliding on a table. It starts sliding at 20 [m/s] and slows to a halt. Assuming that the cup itself is (almost) massless, and that all the energy has gone into heat, what is the final temperature of the water?

Ice with a mass of 0.15 kg at 0.0 degrees Celsius is added to 0.25 kg of water at 20 degrees Celsius in a thermally insulated cup at atmospheric pressure. This approximates to a thermally insulated system of ice and water. Where no heat enters of leaves the system, what is the final (equilibrium) temperature of the system? Give your value in degrees Celsius.

A group of students place a 0.045 kg water sample, initial temperature 21.5 degrees Celsius, on a heat source. The water is then warmed up to its boiling point then further heated until it is completely evaporated. Note: Both the heat source and the water are in a thermally isolated container. i. Find the total heat absorbed by the water during this process. ii. A similar experiment is performed on an unknown liquid, mass=0.055kg with initial temperature 21.5 degrees Celsius....

2. The Rhett Butler Peach, Co. dips the peaches in boiling water (100 degrees Celsius) to remove the skin (a process known as blanching) before canning them. The wastewater from the process is high in organic matter and it must be treated prior to disposal. The treatment process is a biological process that operates at 20 degrees Celsius. Thus, the wastewater must be cooled to 20 degrees before disposal. Forty cubic meters of wastewater is discharged to a concrete tank...
