Lab #11 Calorimetric method Dustin Johnston Physics 118 Spring 2008 Introduction There are two objectives in this lab. One to study the calorimetric method of determining the specific heat of different materials. Second this lab examines the way that you can use measured losses to compensate for error. Procedure During this lab you will use several metal samples, digital thermometer, boiler and a calorimetric vessel. The first step is to measure the heat loss to the environment, to do this first measure the mass of the empty calorimeter cup. Next add hot tap water and measure its mass a second time. Now measure the temperature every ten minutes. Now fill the boiler half full and begin heating it. Measure the mass of the two empty cups, fill one of the cups about 1/3 rd of the way full with cold water and determine its mass by subtracting the mass of the empty cups from the total mass of water and cups. Fill the second cup about 1/3 rd of the way full with hot water

### What students are saying

• 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.
