Combustion

Definition

Combustion is a chemical process that occurs when a substance reacts rapidly with oxygen, releasing energy in the form of heat and light. This process was crucial during the Scientific Revolution as it helped to advance understanding of chemical reactions and laid the groundwork for modern chemistry. Combustion played a significant role in various technological advancements, such as steam engines and other machinery that fueled the Industrial Revolution, stemming from the ideas developed during this earlier period.

5 Must Know Facts For Your Next Test

1. Combustion is classified into two main types: complete combustion, where fuel burns fully with enough oxygen, and incomplete combustion, where insufficient oxygen results in byproducts like carbon monoxide.
2. The study of combustion during the Scientific Revolution led to important discoveries about gases and air composition, particularly by scientists like Robert Boyle and Antoine Lavoisier.
3. Lavoisier is often credited with establishing the law of conservation of mass, which states that mass is neither created nor destroyed in chemical reactions, including combustion.
4. Understanding combustion was essential for the development of engines that powered machinery during the Industrial Revolution, leading to significant advancements in transportation and industry.
5. The advancements in understanding combustion not only influenced technology but also impacted environmental awareness regarding pollution caused by burning fossil fuels.
