DESCRIBE the process that occurs in the following regions of the boiling heat transfer curve:. a. Nucleate boiling. b. Partial film boiling. c. Film boiling. d. Departure from nucleate boiling (DNB). How does heat energy get from the Sun to the Earth?. There are no particles between the Sun and the Earth so it CANNOT travel by conduction or by convection. . ?. RADIATION. How can we relate our new understanding to the greenhouse effect?. Why is it windy at the seaside?. Cold air sinks. Where is the freezer compartment put in a fridge?. Freezer compartment. It is put at the top, because cool air sinks, so it cools the food on the way down.. presence of bulk fluid motion and by conduction in the absence of it. Therefore,. conduction in a fluid can be viewed as the limiting case of convection, corresponding to the case of quiescent fluid (Fig. 6–1).. Dr. . Amal. . Ibrahem. Chapter . Learning . Outcomes.
