# Essays on First and Second Laws of Thermodynamics and Their Applications Assignment

The paper "First and Second Laws of Thermodynamics and Their Applications" is a good example of a finance and accounting assignment. First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.

The Second Law of Thermodynamics states that "in all energy exchanges if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state. " This is also commonly referred to as entropy. A watch spring-driven watch will run until the potential energy in the spring is converted, and not again until energy is reapplied to the spring to rewind it. A car that has run out of gas will not run again until you walk 10 miles to a gas station and refuel the car.

Once the potential energy locked in carbohydrates is converted into kinetic energy (energy in use or motion), the organism will get no more until energy is input again. In the process of energy transfer, some energy will dissipate as heat. Entropy is a measure of disorder: cells are NOT disordered and so have low entropy. The flow of energy maintains order and life. Entropy wins when organisms cease to take in energy and die. Appraise the elementary concepts in combustion: types of combustion, the heat of combustion, combustion temperature and chemical equilibrium.   The investigation of the student's preconceptions brought up several hints to tie up to.

Together with the predictions of the experts, the aim is to find guidelines for the work with elementary school students where their special pre-knowledge is to be considered and included in the didactic requirements given by the experts.
