Homework Statement
nickel weights 28.2g and is heated to 100°C
150g water at 13.5°C
After the nickel is placed in the water, the final temperature of the metal and water is 25°C.
Find the specific heat capacity of nickel
Homework Equations
Q=mcΔT
The Attempt at a Solution
Qwater=mcΔT
=150g x 4.181J/°C x (25°C-13.5°C)
=7212.225J
Qnickel+Qwater=0
Qnickel=-Qwater=-7212.225J
mcΔT=-7212.225J
c=(-7212.225J)/(28.2g)(25°C-100°C)
=3.41 J/g°C
I googled the c value for nickel and it's 0.44 at 25 degrees Celsius. I'm not sure where I went wrong. Thanks in advance for helping
