Forexample in the materials course, students learn about the thermal properties of materialsfrom the atomic viewpoint. Generally, the heat capacity, coefficient of thermalexpansion, and the thermal conductivity are discussed.7 Students are able to describe howand why thermal conduction takes place in metals and insulators as a function oftemperature. The one-dimensional heat conduction equation is used as a means of examiningthe changes in the thermal conductivity, k of various materials. ∂Q ∂T = − kA

move. If we assume that there is no mass movement into or out of the object (or the control volume), we thus define theobject’s energy change as E = E chem + E elas + E motion, rot + E motion, trans + Etherm + Efield, grav + Efield, mag + ... = W + Q, whereW is work and Q is heat transfer. Positive work or heat transfer increase the object’s energy, while negative values decrease it.Now let’s look at a few of these terms in more detail. We start with work, which is related to the force which accelerates the object and how the object responds to that force.If we look at a force pulling a box across a floor (see diagram below), we see that the actual work done is dependent not only onthe force and the amount of movement, but
