the lab (so I can check them off)
Two people per Lab sheet will be okay
o We will transfer ENERGY (calories) to the room temp water; the
energy will be a part of the metal we use to convey this energy.
Remember that the specific heat of water is Cwater = 1.0 calorie/goC
o We will then calculate the specific heat (Cmetal) of the material once we
have determined how much energy the metal gives up.

Lab: Burning Peanut – Calorimetry lab
- If you are allergic to peanuts let me know NOW
- Specific Heat Lab due today
- Get lab handout: each person gets one but if you wish you can turn in with a
partner
o Use the electronic scales to save time but to avoid the line you can use
the triple beam balances
o The burning peanut will heat the can and the water inside (and what
else? --> leading to errors) so you need to know the mass of each item
 we know that water has a density of 1 g/ml so we can use a
graduated cylinder to measure out the mass of water we are
adding to the can 46.5 ml (of pure water) = 46.5 grams (of pure water)
o The chemical reaction is a partial combustion of the peanut (mixture of
mostly proteins and fats) which is why you see so much soot (not enough oxygen to
turn all the carbon into carbon dioxide)
o You have to add enough water (and use a small enough peanut sample) that we
don’t get it boiling or there is more math in the calculations
o Have fun, stay safe, learn lots 
