To identify the three basic mechanisms of energy transfer, describe how
energy is transported by each mode and give an example of each transport
mode.
To distinguish between sensible heating and latent heating.
To describe how temperature and heat are related through the specific heat
of a substance.
To explain the significance of wind-chill and to calculate wind-chill equivalent
temperatures from values of ambient air temperature and wind speed,
using the provided table.
