Question

3. 3. A student set out to determine Using the following the calorimeter constant for the calorimeter to be used in this exercise owing information and the data contained in the table below, manually prepared tp and pencil u co graph paper, not a spreadsheet) a plot of the student's data and calorimeter constant. The mass of hot water, the system in the equation emootC&Tr water, was hot, which was added to the surroundings, in this instance the calorimeter and the cold emined to be 63.812g. The mass of cold water, which was in the calorimeter, was 0.8669. The initial temperature for the hot and cold water will be determined at the line on the best fit lines for each trend of the plotted data. The final temperature for both hot equal to the temperature of the mixture, where the best fit line intersects the line of of mixing based and cold water will be mixing. Subm it the plot with your Pre-Laboratory assignment.
