Chemistry- Wednesday, February 11, 2009

Today in class, we reviwed the activity that we completed yesterday. In general, we found that there were several factors involved in heat transfer within a system:

  1. Mass of the substance (m)
  2. Temperature change (∆T)
  3. Type of substance

The type of substance has a significant effect on how much energy can be transferred between substances. You can get a measure of the ability of a substance to exchange energy by looking at the substance’s specific heat capacity, c.

All this accumulated into the formula q=mc∆T, the formula for heat transfer.
