Abstract Heat is a quantity measured by the addition or removal of heat energy within a system and is observed by the increase or decrease in temperature of the system. Heat is typically represented by Q and is found the equation; Q = mc ∆T . In this equation, heat (Q) is measured in calories. A calorie is defined as a unit of measurement where the amount of eat required to raise the temperature of 1 gram of water at 1 atmosphere pressure within a system. 1 calorie is equivalent to 4.184 Joules. In the lab, a calorimeter system was set up to find the specific heat of two different systems. Students were required to correctly set up and calibrate a calorimeter system and calculate the specific heat of Charger Gold coffee and Columbian Supreme coffee. After conducting the calorimeter test for both coffees and completing the calculations, it was found that the Charger Gold had a higher specific heat of 1.021 calories than the Columbian Supreme which had a specific heat of 0.694 calories. The calculations with the results can be found below in the Data/Tables section. Introduction In this lab, students were required to correctly setup a calorimeter system, calibrate it, and obtain the specific heat of Charger Gold coffee and Columbian Supreme Coffee and figure out which one had a higher specific heat. Four cups were obtained with two lids. Two cups each were stacked together. The two separate stacks, each with a lid, were weighed on a balance and

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
