PPT-Section 2-3: Heat Transfer, The Water Cycle, and Wind

GREAT WEBSITE LINK FOR MODULES https wwwncclimatencsuedu edu k12 eeb Lesson Objective By the end of this lesson you should be able to a Describe the main processes of the water cycle. Scales of Measurement. Celsius scale – based on where water freezes (0. . C) and where water boils (100. . C). Kelvin scale – based on the movement of particles. . Absolute Zero. At 0 K, all particle movement has ceased.

Chapter 3c : One-dimensional, Steady state conduction (with thermal energy generation) (Section 3.5 – Textbook). 2. 3.1 Implications of energy generation. Involve a local source of thermal energy due to conversion from another form of energy in a conducting medium.. ON HEAT TRANSFER COEFFICIENT (h) OF FLUIDS IN CONTACT WITH . SOLIDS OF DIFFERENT TEMPERATURE IN NATURAL CONVECTIVE HEAT TRANSFER. (for Bonus Quiz No. 6 of ME 130 Course on Applied Engineering Analysis). 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?. To Make Foldable:. 1. On the short side of the paper, fold it down an inch.. 2. Now fold it in half, hamburger style.. 3. Now fold it in 1/3.. Conduction. Convection . Radiation. Heat Transfer. Examples. USING THERMAL ENERGY. Thermal Energy. Lesso. n Objectives:. • Explain the relationship between temperature and thermal energy.. • Define heat and specific heat.. Thermal Energy. Lesson Summary:. Heat is the transfer of thermal energy between objects that have different temperatures. . Heat. Heat. is energy that flows from a higher-temperature object to a lower-temperature object because of the difference in temperatures.. SI Unit of Heat:. joule (J).. SI unit for heat is the joule, J. The continuous movement of water . from the . ocean. …. to the . atmosphere. …. to the . land. …. and back to the . ocean. What powers the Water Cycle?. What powers the Water Cycle?. The Sun!. Essential Standard. 6.P.. 3 Understand . characteristics . of energy . transfer and interactions of matter and energy.. Clarifying Objective. 6.P.. 3.1 Illustrate . the transfer of heat energy from warmer objects . 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.. . Eng. . Abdelrhman Essam. Free convection and Radiation. Convection . Convection Heat transfer can be classified into;. 1- forced convection . 2- free convection.. Introduction to free convection. Dr. J. . Badshah. Professor and Head, Dairy Engineering.
