Question

Write two uses of each of following?
Heat energy
Electrical energy
Sound energy​

Answer 1

Heat energy :- Rubbing of two objects cause friction to produce heat energy. Heat is used to make things warm, to boil water and fry eggs and to melt metal to build cars. Heat is used to generate electricity at a thermal power plant for our daily lives. Temperature is the measure of how hot or cold matter is.

Although we cannot use sound energy to power our cars or light our homes, we can use sound energy to learn about our surroundings. The simplest and most obvious use of sound energy is for hearing.
