Equilibrium temperature homework

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

Hello,

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?
