Detailed Solution

The given statement is true.
Concept- Locate examples from your surroundings by relating to the specific terms in the question. Electrical in this context refers to the electrical grid and the electrical devices in your immediate environment. Chemical energy conversion occurs in a limited number of locations.
(1) Electrical Energy to Kinetic Energy: This process of converting energy plays a significant role in our daily lives. They are much more significant than we realise. The conversion of electrical energy to kinetic energy can be seen in your kitchen's juicer, the electrical pump that carries water to your water tank, elevators, or even the fan you are currently sitting beneath.
(2) Chemical Energy to Electrical Energy: Although it may be challenging to locate, this form of energy conversion is much more accessible than you might realise. Your phone and the laptop you're using to study right now are powered by them. The battery is responsible for transforming the chemical energy into the necessary electrical energy.
(3) Sound Energy to Electrical Energy Conversion: For a group of very many individuals who desire to communicate with one another, this energy conversion is nothing short of a blessing. A microphone is a device that transforms sound energy into electrical energy, which is subsequently transformed back into sound energy by speakers after being amplified.
Hence,the given statement is true.
