Homework #1 Solution 1. Conduction or conductive heat transfer is energy transfer within a stationary fluid or solid. Radiation or radiative heat transfer is energy transfer by electromagnetic waves or photons. Convection or convective heat transfer by bulk fluid motion. 2. (a) Thermal conductivity is a material property that is the ratio of the temperature gradient to the heat flux if the material is stationary. OR thermal conductivity is a material property that is a measure of the rate that heat conducts through the medium.
