## 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
