Answer:
There is a whole bunch of energy trans formation taking place, layers and layers in fact:
First an elecric motor transforms electricity into kinetic energy and thermal energy.That motor turns a magnatron converting producing a specific band width of microwaves particularly well tuned to heating water molecules.
Those microwaves are doing all sorts of stuff:
Most are bouncing off the reflective surface of the fan blades attached to the motor/magnatron assembly and walls of the appliance but some of them are absorbed increasing the energy level and heat of the molecules of those surfaces (kinetic and thermal energy).
Then most of those bounced microwaves hit the food or food vessel the food is in. Some of those photons are absorbed being transferred to kinetic and thermal radiation at a new wave length and some go on their merry way.
Some of those microwaves pass by water molecules which, because water molecules have a polar charge, start spinning, causing transfer of em energy to kinetic energy and then kinetic energy to thermal energy. So again you get kinetic and thermal effects.
What give microwave cooking its unique characteristcs is the interplay between mucrowaves and water in the food. Microwaves are very, very efficient at heating water. So when you microwave food you are effectively steaming the food in its own juices.

Answer:
It is a Electromagnetic Wave, which does not need a medium to travel through, so radio waves travel through space or a vacuum.
Explanation:
Types of Electromagnetic Waves
Radio Waves. Radio waves have the longest wavelengths of all the electromagnetic waves. ...
Microwaves. Microwaves are shorter than radio waves with wavelengths measured in centimeters. ...
Infrared. Between microwaves and visible light are infrared waves. ...
Visible light. ...
Ultraviolet. ...
X-rays. ...
Gamma rays. ...
I can give 1 but indetured servants is an optional thing people were payed but very little to do it
Answer:
In india, china, teachings
Explanation:
Ashoka promoted Buddhist expansion by sending monks to surrounding territories to share the teachings of the Buddha. A wave of conversion began, and Buddhism spread not only through India, but also internationally.
Got this answer from the web.
The answer is: The sea
Back then, the techology that exist to travel by sea was not as developed as it is today. If an empire decided to travel through the sea in order to do some conquests, that empire will risk several things, such as:
- Loss in directions
- The ships could be swallowed by harsh wheather in the middle of the sea
- It need a lot of resources to maintain the armies during the travel
