Thermal equilibrium and aluminum

  1. Jun 16, 2009 #1
    (This is not a hw question....it's a theoretical question based on an experiment that was conducted.)

    If you have an aluminum block and a copper block of equal mass, but the copper block is 100 degrees C and the alum. block is 0 degrees C, they reach roughly 30 degrees C at thermal equilibrium according to an experiment.

    So as you can see, the aluminum block influenced the final temp, since the final temp was closer to aluminum's initial temp. Why is this? Is it because aluminum is a better insulator of cold?

    Check the heat capacity per gram. Aluminum is 2.35 x larger.
