Conservation of Energy Principle Correct Answer-During an interaction, energy can change from one form to another but the total amount of energy remains constant. i.e. Energy cannot be created or destroyed. First Law of Thermodynamics Correct Answer-The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from ...
