Detailed explanation-1: -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. These produce a change of stored energy within the control volume.

Detailed explanation-2: -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-3: -The first law of thermodynamics states that the energy of the universe remains the same. Though it may be exchanged between the system and the surroundings, it can’t be created or destroyed. The law basically relates to the changes in energy states due to work and heat transfer.

Detailed explanation-4: -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. Hence the statement is correct.

Detailed explanation-5: -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.
