Homework Statement
I'm having a problem in solving specific heat equations. I get the basic concept and know the formula, but in doing the sample problems, I can't seem to get them right. I have a lab assignment where I need to find the specific heat capacity for Fe. I have all the required information filled in on the observation sheet.
Here's the problem:
Mass of Fe: 100gm
Volume of water in calorimeter:
Mass of water in calorimeter:
Initial Temp:20 degrees C
Final Temp: 100 degrees C
Final Temp of both the metal and water: 100 degrees C
Determine the heat gained by the water (show your work)
Q water=
Q Fe=
Homework Equations
Q= C(specific heat) x Mass x change of temperature
The Attempt at a Solution
What I have done so far is
Mass= 100
C= 0.108
Tf= 100 C
TI=20 c
from there Q=100*0.108*80= 864 (I know somethings wrong with that answer)
I think it has to do with C, I tried finding the Specific heat of Iron online and came up with several different answers
