Answer 1

1. The energy chain concept is defined as energy paths from source to energy. consumption to final end-use energy benefit in terms of heating, cooling, lighting and other benefits of energy. (a) Concept of Entire Energy Chain. (b) Indices Definition.

2. the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.

3. That "something" is energy. When you use a hammer to pound a nail into a board, you transfer kinetic energy to the hammer and the hammer transfers that kinetic energy to the nail. ... For example, sound energy is produced when you hit the nail.
