Homework Help: Equilibrium temperature homework

  1. Nov 28, 2007 #1
    4. When 1 kg of water at 1000C is mixed with 10 kg of water at 00C, the equilibrium temperature will be:
    a) exactly 00C b) exactly 500C c) exactly 1000C d) slightly above 00C

    5. Two objects, A and B, have the same mass and the same initial temperature. However, object A has a smaller specific heat capacity than object B. If the same amount of heat of heat is added to each object, then:

    a) both objects will have the same final temperature
    b) object A will have the higher final temperature
    c) object B will have the higher final temperature
    d) we need the values of the specific heat capacities to determine which object has the highest final temperature

    I think they typically like to see a bit of effort before posting answers. With these problems, you should be able to at least eliminate some choices with some simple reasoning.

    For instance, in #4, what happens when you pour a little bit of hot water into a whole lot of cold water? Can you eliminate any answers based on your intuition? If you're not sure, you can always try it at home :-)

    For #5, what exactly is the definition of specific heat capacity? Does this help eliminate any potential answers?

    What are your thoughts on these?
