Chemistry lab round 2

Morning!

Yesterday we did our second and final chemistry lab, and its finally over. The lab was about calculating the amount of energy lost when a certain alcohol heated up 100cm3 of water by about 40°C. We used four different types of alcohol: Propane, Ethanol, Methanol and Butanol. The alcohols produced flames of different sizes which didnt depend on the type of alcohol, but more like the size of the wick. It took about 4 minutes to heat up the water by 40°C, just a side-note. 

During the lab, we ran out of matches several times. But somehow Peter always managed to come back with some more. Even though he repeatedly accused some of us of having a box of matches in our pockets. When we finally asked him where he got the matches from, he gave us a list. Since this blog is for you guys, we thought we might share the list with you. So here it is: 

The various places Peter got the matches from: 
- Marietta's Café
- Teachers Kitchen
- Roger Lister's desk
- Uli Niebergall's pocket
- Fredrik Nylund's pocket

Here is a picture, the only picture that we were actually able to upload (thank you first graders), which shows Peter drawing some really funny pictures of students and teachers!

Check out his evil laughter.
