1. The problem statement, all variables and given/known data So I've been trying to find the specific heat capacity of the potato for a while and keep coming up with an outrageous number (over 700,000 J/kgC) Here's what I've found mass of potato = 0.15kg initial T of potato = 18 degrees C final T of potato = 83 degrees C (is this not hot enough?) therefore change in T is 65 degrees C The power rating of my oven is 2000W, and I cooked it for 3600 seconds. 2. Relevant equations I found the Q value by multiplying the oven's power by the time in seconds, so Q=7,200,000J I then used the equation c = Q/m∆T for the specific heat capacity 3. The attempt at a solution c = 7200000/(0.15)(65) = 738462 J/(kg degrees C) We haven't done anything in my IB class about this subject, but I'm pretty sure that this number is way too big, and I can't figure out what to do, so I'm obviously missing something… Any suggestions? Thanks!
