Specific Heat Problem: PLEASE *delete me*!!
« on: June 24, 2007, 08:52:00 PM »
A 165.0 g sample of metal at 75.0 'C is added to 175.0 g of water at 15.3 'C. The temperature of the water rises to 22.3' C. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is gained by the water.


I dont know where to start this problem and what to do. Please help.

Energy in the form of heat lost = energy in the form of heat gained.
Or, Q1=-Q2
Or
Q1 + Q2 +... = 0

Where Q = m*C*ΔT (mass, specific heat, change in temperature).

How much heat does it take to raise the temperature of 175.0 g of water from 15.3oC to 22.3o?
