|Life depends on an essentially continuous exchange of mass and
energy between living organisms and their environment. Human
impact on this vital exchange has occurred on a global or
macroclimate scale. Understanding the physical principles
involved in heat transfer and absorption in the atmosphere is
critical to understanding how these physical factors affect
living organisms. The specific objectives of this section are to
explain the properties of heat transfer, and to describe
laboratory activities that can be used at a variety of academic
levels with only slight Described below are three series of
experiments performed in the laboratory to address questions
that emphasize the underlying principles of heat transfer. These
hands-on experiments focused on principles that relate to
conduction and convection. The object was to identify the method
of heat transfer through solids, liquids, gases, and between
boundaries. Understanding these concepts gave us a better
understanding of how heat is transferred betwee
