Experiment I: Thermochemistry Background: Thermochemistry is the branch of chemistry that focuses on the studies of chemical reactions or physical changes and heat associated with chemical reactions. According to the first law of thermodynamics‚ energy cannot be created or destroyed but it can be converted from one form into another and/or transferred between different atoms‚ molecules‚ or substances. In general‚ energy can be classified into two categories: kinetic and potential. Kinetic energy

Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion
