Conduction is..... heat transfer through liquids and gasses (forms a current). heat transfer through touch. used in a microwave. used in an oven. Convection is..... heat transfer through liquids and gasses (forms a current). heat transfer through touch. used in a microwave. produced by the sun. Radiation is..... heat transfer through liquids and gasses (forms a current). heat transfer through touch. felt by touch felt next to a fire. Food being heated from touching a hot pan. conduction convection radiation Hot air from a blow dryer. convection radiation conduction Food being heated in a microwave. conduction convection radiation Hot air making a hot air balloon rise. convection radiation conduction conduction Heat from standing next to a fire. convection radiation Egg cooking from the heat of the sidewalk. convection radiation conduction A warm chair from someone sitting in the seat. convection radiation conduction Boiling water. convection radiation conduction Heat from sitting next to a space heater. convection radiation conduction Heat always moves from hot to cold Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only Energy always moves from high energy to low energy. Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only The transfer of energy or heat through direct contact Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only The transfer of heat through liquids or gasses. Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only The transfer of heat through electromagnetic waves. Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only The sun's rays heating the earth. Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only Cooking food using a pan on a stove. Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only Cooking food in an oven. Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only It can be felt standing close to a fire. Conduction only conduction, Convection and Radiation (all three) Convection only Radiation only Mr. Boyd went camping during Christmas break. It was cold outside and he built a small fire. He held his hands OVER the fire to warm them up. Mr. Boyd warmed his hands up using mostly... conduction radiation convection all three Mrs. Ruble was working on her dirt bike in the garage. It was a bit chilly in her garage so she turned on her space heater. She placed the space heater NEXT TO HER so she could feel the heat from it. Mrs. Ruble is using..... conduction convection radiation What methods of heat transfer are represented in this picture of a wood burning stove / oven. Conduction Convection Radiation All of the above |
