Specific Heat Capacity

Postby Patrick Wilson 2B » Sun Feb 12, 2017 10:10 pm

There is a question from the homework that asks for the heat required to raise the temp of 400g of water and 500g of cu to 100 degrees celsius and how much of the heat (%) goes into just heating the water. How do we know the specific heat of cu ? Is this an open system? What is the best way to set this up? Thanks!

I just assumed it was under closed conditions and make q(total)=q(Cu)+q(H2O). Then sub out for the actual equation: q=mC(sp)deltaT+mC(sp)deltaT. Plug in the values for mass, the given specific heat capacities of Copper and water and the change in temperature is the same for both.

For this problem, you would be given the heat capacity for Cu, it is in the Appendix of the textbook.
