The Sun’s Brightest Secret: Nuclear Fusion
Chemistry
Energy
Hydrogen
The sun continuously undergoes atomic fusion to generate energy. The sun’s core contains hydrogen and can reach temperatures of 10-15 million degrees Celsius. The production of helium generates enough energy to support life on our planet. Various fusion reactions are used for energy production on Earth, with each chosen based on its suitability. Occurs between…
Chemical And Electrochemical Machining
Chemistry
Chemical machining ( CHM ) is a untraditional procedure in which stuff remotion occurs through contact with a strong chemical etchant. Applications as an industrial procedure began shortly after World War II in the aircraft industry. The usage of chemicals to take unwanted stuff from a workpart can be applied in several ways, and several…
Basic Cooling System Theory
Chemistry
Heat
Temperature
The internal combustion engine is a very inefficient way to power a car. Most of the energy of the fuel is wasted creating heat. This heat, if not removed, will quickly cause the engine to get so hot that the metal parts will melt. The cooling system is there to remove that excess heat. As…

Radon is an element that is on the periodic table of elements. It is a member of the family called the noble gases, which is group number 18. Radon is a gas. It is a gas at 298 k. it is the heaviest known mononuclear gas at that temperature. Radon is also colorless. When it…
Deicer Magnesium Chloride
Chemistry
Melting Point
Water
Abstract A common road salt, magnesium chloride, was analyzed in the lab to test its effectiveness as a road salt. The Van’t Hoff factor of the salt and the enthalpy of dissolution when dissolved in pure water were experimentally tested to evaluate its many characteristics as a deicer. To determine the Van’t Hoff factor, the…

Water
My hypothesis is that dissolved Phosphate will change for the total phosphorus when left under a light. I believe that suspended phosphorus has the biggest impact on the eutrophication of lakes. When there is an increase of phosphorus in lakes, this leads to and increase in phytoplankton. This then leads to a decrease in water…
