How is heat transfered by radiation different from conduction and convection?
Radiation does not need any material medium to transfer energy where as the other two conduction and convection need a material medium to perform.
How is heat transfer by radiation different from both convection and conduction?
The main difference is that radiation can travel through any medium. Therefore, it is different.
Why is solar energy transferred to earth by radiation not convection?
Convection takes place through a material medium between source and sink. There isn't any material medium between sun and earth, and we are therefore thankful that radiation exists.
Can heat travel by convection through a vacuum?
No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.
What is heated by radiation?
Radiation is a method of heat transfer that does not rely on any contact between the heat source and the heated object (as is the case with convection and conduction) Examples of radiation is heat from the sun or from the fliament of a light bulb
Can you use metal in a convection oven?
Typically, you cannot use metal in a microwave oven. In combination type microwaves however, you can use metal as long as it is in convection mode.
Where can you buy a microwave-convection oven combination?
I bought a microwave-convection oven at Sears, but you can find them at any good-sized appliance store.
Are there any other types of heat transfer?
There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
Is there any radiation from a game controller?
Pfft. No. It uses Radio Signals. Not Radiation.. Radiation is from the Sun and Microwave Signals. :)

Does this convection microwave include any baking trays?
No baking trays are included with this product.
How is heat transfered by radiation different from conduction and convection?
Radiation does not need any material medium to transfer energy where as the other two conduction and convection need a material medium to perform.
Is Microwave radiation of very high intensity harmful?
Yes, radiation of any frequency can be harmful when it is intense enough.
How is heat transfer by radiation different from both convection and conduction?
The main difference is that radiation can travel through any medium. Therefore, it is different.
Are microwave cooked foods dangerous?
Not at all. Food cooked in the microwave does not contain any microwave radiation. However, you could burn your mouth if, for example, you heat a danish in the microwave and bite into it too soon as the bready outer part can seem cool enough to eat while the filling is still dangerously hot. But on the other hand microwave use the same wave lengths as xrays and such and could possibly harm you depending on the age of the microwave.
Can microwave cooker radiation cause congenital emphysema?
No. The word "congenital" means "from birth," so that type of emphysema would result from an inherited trait or tendency, not from any environmental source like microwave radiation.
Why is solar energy transferred to earth by radiation not convection?
Convection takes place through a material medium between source and sink. There isn't any material medium between sun and earth, and we are therefore thankful that radiation exists.
