Chemistry Lab Report Determining Best Calorimeter Dylan Mendonca 12-B Background: Calorimetry is the science of measuring the heat of chemical reactions or physical changes. Calorimetry is performed with a calorimeter. A calorimeter can be any container from a cup to a Calorimeters need to be well insulated as calorimetry relies on the fact that temperature change only occurs within the solution and that no heat escapes to the surroundings. That is why it is important that calorimeters are well

There are two useful numbers that you can compute with the EAC. One of them is called Estimate to Complete (ETC)‚ which tells you how much more money you’ll probably spend on your project. And the other one‚ Variance at Completion (VAC)‚ predicts what your variance will be when the project is done. ETC = EAC - AC €11‚ 507 – €5‚ 750 = €5‚ 757 (how much the rest of the project likely to cost) Since EAC predicts how much money you’ll spend‚ if you subtract the AC‚ you’ll find out

Formula for Grade Average Calculation There are 3 grade averages: TGA‚ CGA and GGA. TGA (Term Grade Average) is the combined grade average covering all courses taken in the term and the session immediately following. CGA (Cumulative Grade Average) is computed based on all the courses taken by the student which are expected at the time of calculation to be applied towards the degree requirements in the current program. TGA & CGA = Sum of (Course Credits x Course grade points) Sum of Course Credits
