research the chemistry behind a chemical reaction that is used in automobiles. Write a page that explains what the reaction is, where it occurs in the car, and what it does for the car.

There are over one billion of cars around the world, getting people where they want to go. Therefore, automobile transportation became much more important in everyone’s daily life. Chemistry made the automobiles to work. The chemistry and chemical reactions used in many parts of the automobiles. The role of chemistry in the automobile includes air bags, starting a car, gas, windshields, combustion and batteries. The most important among all these is keeping the automobile’s engine from getting too hot or too cold.

The process of starting the car begins in the engine cylinders, where gasoline from the fuel injector and the air from the intake valve mix together before being ignited by a spark and form gasses that expand and push the piston. But combustion is an exothermic reaction, which means it release heat. In this process, a lot heat will be released and much of this heat will be escaped through the tail pipe.

The heat that remains in the engine block need to be absorbed, transported and dissipated to protect the metal components from deforming or even melting. Therefore, the cooling system will used to prevent the deforming of metal parts or melting of metal components. In this cooling process, a liquid gets circulated throughout the engine. We have to use a liquid that can absorb all that heat. A homogeneous mixture consisting of a solute and a solvent based on colligative properties, which means solution’s properties will differ depend on the proportion of solute present. Solutions have both a lower freezing point and a higher boiling point than pure solvent. The more solute is present the bigger the difference between the freezing point and the boiling point. To explain furthermore, we need to understand that temperature is the measure of the particle’s average...
