The microwave undergoes a variety of energy transformations when you are heating food.
Starting from electrical energy (obtained via the mains power point/wall socket), the energy is transformed into microwave/thermal radiation (electromagnetic radiation/energy). These 'microwaves' react with the water particles in the food and cause them to vibrate. The friction produced by these vibrations produces heat and ultimately cooks/heats up your food.
However, there is some energy that is transformed into light (the light you see when the microwave is one), sound (that humming noise you hear when it's operating) and kinetic energy (the rotating disk inside the microwave).
Energy is transformed from electrical to heat, sound and light (if the microwave has a light).
Energy is transferred to the food via the process of convection.

Energy transformations for a microwave?
Electric energy turns into microwaves, which then is absorbed as heat.
Is the energy transformations in a car's engine an example of multiple transformations?
Yes. Chemical energy to mechanical and electrical energy and then mechanical energy to kinetic energy.
Is the energy transformations in a car engine are an example of multiple transformations?
Yes. Chemical energy to mechanical and electrical energy and then mechanical energy to kinetic energy.
Are energy transformations in a car engine an example of multiple transformations?
yes because three times of energy transform
What are energy transformations?
=electric fan-electrical energy to mechanical energy!=

Most energy transformations produce what form of energy?
In most energy transformations, part of the energy is wasted. Much of the wasted energy is usually converted to heat.
