Is heat transferred from a microwave to the food is a example of conduction?

No. It is an example of radiation. The heat is transferred by microwaves, which are a form of electromagnetic radiation. Conduction occurs when two objects of different temperatures are in contact or when different parts of an object have different temperatures.

When you burn your finger by touching a hot stove you have experienced heat transfer by what?
There are 4 types of heat transfer, convection, conduction, radiation, and direct flame contact. When you touch the stove the heat is transferred directly from one body, the stove, to the other, the finger. This is heat transfer by conduction.
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.
Why does a plate become hot when hot food is placed on it?
"conduction"
What is the function of a microwave?
to heat up food
What are all of the things that a microwave do?
cook all your food and heats it up and unthaws food
How does conduction occur in an oven?
If the food directly touches something (e.g. pan, oven grate, oven walls, red hot electric element) heat is transferred by conduction.
What is the name of the process by which heat is transferred through the walls of a oven?
Heat is transferred by convection and by radiation in a conventional gas oven. In an electric oven heat is transferred by radiation only. In a microwave oven, radar waves bombard the molecules within food, bouncing them around enough that the friction produced causes heat to build up within the food.
What energy transformation occurs in an oven?
The electricity (electromagnetic energy) that drives the microwave oven is routed to the magnetron, which generates the microwave energy. (The electricity and microwave energy are both forms of electromagnetic energy.) The microwaves travel through a waveguide into the cavity (the cooking space) in the oven, and used to excite chemical bonds in the food items. This is a conversion of microwave energy (electromagnetic energy) into the mechanical energy of heat.
What happens to solid food when in the microwave to long?
If the microwave is not energized, then the food will spoil. If the microwave is energized, then the food will burn.
What can you reheat in a microwave that you cannot in an oven?
You can heat any food in an over that you would in a microwave, you'll just have to put it in an ovensafe container. For example, you can't put plastic in the oven but it works in a microwave.
What is example of real-life waves?
Do you have a microwave?(hint hint!) they use microwaves to cook food.
Example of how conduction is used in daily life?
In cooking the heat from the hob transfers to the pan therefor cooking the food
How must microwaves interact with matter if they cause food and most containers to heat up in a microwave oven?
The waves of energy must be absorbed by the food so that the energy the wave was carrying is transferred as heat.
Example of electrical energy to electromagnetic?
a microwave or a x-ray. Because when the microwave for example is plugged in or turned on is electrical energy and when the food is being cooked is when electromagnetic energy is used. Hope I Could Help :]
If you put a pot on the stove the pot becomes hot. The heat is transferred to the pot on the burner by radiation. Please select the best answer from the choices provided T F?
It depends on the size of the flame. If the flame is large enough so that it touches the bottom of the pot, the heat is transferred directly from the flame to the pot by conduction. A smaller flame will radiate heat to the pot but will also heat the air between the flame and the pot (by conduction) and the hot air will also transfer heat to the pot by conduction. Either way, heat moves from the bottom of the pot to the rest of the pot and the food inside by conduction.
What are the different theories of water and food conduction in plants?
what are the different theories of water and food conduction in plant
Example of conductivity?
some examples of conduction are: 1.using a metal stove to cook food 2.making a glass blower's pipe 3.cooking on electric stove top 4.making a car radiator 5.closed circuit steam engine
