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...
