Describe the energy transformation that must take place for a microwave to warm up a slice of pizza

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.

Explanation:

Electromagnetic waves transmit heat to the pizza.

i took a test and it had a question like this

the cost of college has risen faster than inflation for many years.

the high price of student services and administration are two reasons for the rapid increase in cost.

the hebrew bible is the sacred text of judaism;

the koran is that of islam.

among eastern religions, the sacred scriptures of hinduis are the four vedas and the upanishads, among others.

a main characteristic in these books is that un most of them we find certain "norms" of behavior, as is the case of the bible that has it's commandments. these rules are to regulate the behavior of believers and faithful of their respective faith.

these rules tell us what is right and what is not.
