Calorimeter Lab help
« on: May 26, 2008, 01:59:39 PM »
Can someone double check my work?

I am doing a lab, that ask to come up with Ccal for the calorimeter, using a mixture of hot and cold water. My calculations are:
Cold water temp = 21.00 C
Hot water temp  = 92.20 C
Mixture temp     = 55.8 C

Qinitial = 9472.6 j
Qfinal  = 9338.7 j
Qcal   = 133.9 j
Ccal   = 3.85 j/DegC
