Question

Give an example for each of the following energy conversion: (1) electrical energy to kinetic energy. (2) chemical energy to electrical energy (3) sound energy to electrical energy

Answer 1

Hint:Relate to the particular words given in the question to find the examples from your surroundings. Electrical here relates to the electrical grid and the electrical appliances from around you. Chemical energy conversion can be found in rather small places.

Complete step-by-step solution:
(1) Electrical Energy to Kinetic Energy: This type of energy conversion forms a major part of our lives. They are way more important than we think they are. The juicer in your kitchen, the electrical motor to pump the water to your water tank, be it the elevators or be it the fan under which you are sitting now, they are all the examples of the Electrical Energy to Kinetic Energy conversion.
(2) Chemical Energy to Electrical Energy: This type of energy conversion may be a little tricky to find but it is way closer to you than you think. They are powering your phone or laptop you are studying on right now! It is the battery, which converts the chemical energy into the required electrical energy.
(3) Sound Energy to Electrical Energy: This energy conversion is no less than a blessing for the group of extremely large people who want to communicate with each other. A microphone is a device, which converts the sound energy into electrical energy and then this sound is amplified and again converted from electrical energy to sound energy using the speakers.

Note: Electrical energy can be related to almost all the appliances you plug in the wall socket. Chemical energy can be related to many of the digital devices you use on a daily basis. There are many inventions going on today for the conversion of sound energy into other useful forms.
