Importance of the Laws of Thermodynamics in the Field of Chemical Sciences
Abstract: The Laws of Thermodynamics are important because they control interactions of everything in the universe - regardless of scale. These rules stretch across every form of science known to humankind. Classical physics is, from a certain perspective, entirely based on Newton's Laws of motion. The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law …

Laws of Thermodynamics Challenge Greenhouse-Gas and CLIMATE- change Hypotheses
Abstract: The greenhouse-gas hypothesis (GGH), i.e., CO2 is the cause of global warming by ~1K from ~1950-2023, is popularly believed to be established scientific truth. It is generally assumed that heat emissions from global fuel combustion are, by comparison, negligible. An application of the Hess-Gibbs 1st law of thermodynamics, however, shows that the enthalpy (H) output from yearly fossil fuel consumption is seven times greater than the H- increase of hypothetical …
