Homework Statement
Calculate the calorimeter constant
50 ml H2O = 50g
Starting Temp for hot water = 52.3°C
Starting Temp for cold water = 21.8°C
Final Temp = 41.3°C
Change in Temp = Hot = -11°C / Cold = 19.5°C
Homework Equations
Q = mcΔT
The Attempt at a Solution
Q = (50g)(4.184)(11) = 2301 J
Q = (50g)(4.184(-19.5) = -4079 J
2301 - (-4079) = 6380 J
6380J / 19.5 = 330 J/C
Now my main questions is since the cold water is gaining heat would the joules be negative or positive.
