			:The Heat of Combustion is a field with a very interesting and long history. Early scientists like Robert Boyle and Joseph Priestley have made interesting breakthroughs into understanding how oxygen is involved within combustion, which as we learned is an essential source within combustion reactions. Priestley discovered oxygen in the 1770s which was a very large initial step made towards our eventual much more complete understanding of combustion.

	:In 1840, Russian chemist Germain Hess proposed that the summation of enthalpy between the initial reactants of a multi-step reaction and the final products was the same no matter the pathways taken. He proposed that the change in enthalpy was a state function, and thus did not depend on the pathway taken so long as the overall reactants and products are the same. He experimented on the hydrates of sulfuric acids and determined that the heat released was the same no matter the path taken. He was a primarily experimental chemist and was concerned with how the affinity of molecules impacts its release in thermal energy.		:In 1840, Russian chemist Germain Hess proposed that the summation of enthalpy between the initial reactants of a multi-step reaction and the final products was the same no matter the pathways taken.

	There are many interesting industrial applications of heat of combustion within the real world. For example, let's look at Energy Production. Within various power plants, it is necessary to calculate/know the calorific value of different fuels, whether coal or natural gas. Knowing this enables us to optimize the various aspects of the combustion process.		:There are many interesting industrial applications of heat of combustion within the real world.

	A large area of the field of computing is computational science, which is applying computer science and mathematics to better understand and model physical systems. With many recent breakthroughs in machine learning algorithms and our ability to use data driven-approaches to solve real world problems, we can train models on physical data to better understand our world around us. Using a combination of known physical properties and novel computing techniques, we can better understand the world around us and make interesting breakthroughs. A great example of the intersection of physics and computing is the 2024 Physics Nobel Prize.		:A large area of the field of computing is computational science, which is applying computer science and mathematics to better understand and model physical systems.

	:Determining the heat of combustion of a fuel is essential when it is used an Energy source. Rockets, for example, convert chemical energy into gravitational potential energy and kinetic energy. Thus, knowing the necessary fuel to accomplish an escape speed without using too much space is critical. Chemical reactions are key as an energy source whether they provide electrical energy or thermal energy. My interest in health also contributes to enthalpy formation, specifically with the macromolecules our body prioritize to store energy. The bonds in carbohydrates do are more readily reactive and thus have a lower heat of formation than carbohydrates. Despite their composition have similar molecules, the bonding of each allows for a larger heat of formation when fats are consumed than when carbohydrates are, leading them to be stored as they are a better source of energy for less space.		:Determining the heat of combustion of a fuel is essential when it is used an Energy source.
