Specific Heat

Postby Kathleen Vidanes 1E » Sun Jan 21, 2018 4:29 am

In discussion, we determined the initial temperature of a piece of copper that was dropped into water given the mass of Cu, volume of H2O, initial temperature of H2O, the specific heats, and final temperatures. The initial temperature turned out to be a much greater number that the final temperature, and this was said to be possible due to the large differences in the specific heats given. How do the differences in specific heats relate to such a large temperature change?

If a substance has a large specific heat, that means it required a lot of energy input to raise its temperature by 1o C. If you need a large change in temperature, say 10 oC, you will need to put in ten times the amount of energy needed to raise it by just 1 degree.
