Detailed explanation-1: -First law of thermodynamics states that total energy of an isolated system is constant, energy can neither be created nor be destroyed but can be transformed from one form to another.

Detailed explanation-2: -The first law of thermodynamics states that energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is associated with mass crossing the control boundary, external work, or heat transfer across the boundary.

Detailed explanation-3: -Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained-it is only transformed. The Second Law of Thermodynamics states that entropy constantly increases in a closed system.

Detailed explanation-4: -In mechanics, there are three fundamental quantities which are conserved. These are energy, momentum and angular momentum. If you have looked at examples in other articles-for example, the kinetic energy of charging elephants-then it may surprise you that energy is a conserved quantity.

Detailed explanation-5: -In physics, 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. Energy can neither be created nor destroyed; rather, it transforms from one form to another.
