Essential Question How does heat transfer affect weather?

http: //www. deltat. com/ways_to_transfer_heat. html

Conduction happens fastest in metals. convection happens in fluids (liquids and gases). Hot fluids rise and cold fluids sinks Radiation is heat transfer by electromagnetic radiation. Radiation heat transfer can happen even in space. http: //www. johnsonwindowfilms. com/dealer/article. View. php? ARTICLE_ID=148 http: //okfirst. mesonet. org/train/meteorology/Heat. Transfer. html

Radiation- heat travels in a vacuum. 1. What are three types of heat transfer? 2. How is heat similar to seismic energy? Think! 3. How is heat transferred from the Sun to you? The Sun is 93 million miles of empty space away from us. Think!

1. What are three types of heat transfer? Radiation, convection, and conduction 2. How is radiation heat transfer similar to seismic energy? Think! They are both waves. 3. How is heat transferred from the Sun to you? The Sun is 93 million miles of empty space away from us. Think! Because heat can travel in the form of electromagnetic wave.

convection – WARM AND MOIST air rises convection – http: //www. weatherquestions. com/What_is_convection COLD AND DRY air sinks

Warm: Carbon monoxide Convection – heat transfer in gases. Cold air (nitrogen, oxygen, and other gases) http: //www. nist. gov/fire_behavior. cfm

Convection – hot gases and liquids rise and cold gases and liquids sink. 4. What is bouyancy ? 5. What is convection? 6. Why is the furnace located in the basement and not in the attic? Think! 7. What happens to water and air when heated? 8. What are fluids?

Convection means hot gases and liquids rise and cold gases and liquids sink. Convection: http: //www. youtube. com/watch? v=Ife. Ra. Ob_E-s Fluids refer to liquids and gases.

4. What is buoyancy ? Buoyancy states that if an object is denser it sinks and when it is less dense it rises. 5. What is convection? Convection means hot gases and liquids rise and cold gases and liquids sink. 6. Why is the furnace located in the basement and not in the attic? Think! Because of convection. If the furnace is in the attic then the basement will be freezing.

7. What happens to water and air when heated? When water and air are heated they become Less dense and they rise. 8. What are fluids? Fluids refer to liquids and gases.

Conduction is the transfer of heat by colliding particles. 9. Which is a better conductor metal or glass? 10. Why are metals considered as the best conductors? 11. What is conduction?

Conduction is the transfer of heat by colliding particles. Metals have free electrons making them the best conductors. Conduction: http: //www. youtube. com/watch? v=9 jo. LYfayee 8

9. Which is a better conductor metal or glass? metal 10. Why are metals considered as the best conductors? Because metals have free electrons. 11. What is conduction? Conduction is the transfer of heat by colliding particles

B 21. Heat transfer in liquids and gases. C 22. Heat transfer without the need of a medium ( solid, liquid, gas). A 24. Flow of heat by physical contact. B 25. Heat transfer in fluids. C 26. Heat transfer through space. C 27. Sunlight travels 93 million miles to reach earth. B 28. Warm air mass from the Gulf of Mexico rises towards the East coast. B 29. Cold air mass from the North sinks towards the East coast. A 30. The engine of the car is very hot. A 31. In the beach, the sand becomes very hot during summer. B 32. Warm air has more water vapor than cold air.
