Which of the following is NOT a result of present heating?

The electrical equipment that turns an electric current into heat is known as an electric heater, electric blub (with filament), or electric iron.

They operate on the Joule heating effect theory.

When an electric current flows through a resistor, it converts electrical energy into heat energy.

Microwaves are used to heat food in a microwave oven..

The generally utilized radio wave frequency in microwave ovens is around 2,500 megahertz ( 2.5 gigahertz).

Water, lipids, and carbohydrates absorb radio waves in this frequency range. They are turned immediately into atomic motion or vibration when they are absorbed.

Heavy motion or vibration is therefore transformed into heat.

Most polymers, glass, and ceramics do not absorb microwaves.

The resonance frequency of water is equivalent to the frequency of the microwave. As a result, the oscillation of water molecules might heat up meals.
