FAQs on Combustion Video Lecture - Science Olympiad Class 7

1. What is combustion?
Ans. Combustion is a chemical process in which a substance reacts rapidly with oxygen and releases energy in the form of heat and light. It typically involves the burning of fuels like wood, coal, or gas.
2. What are the types of combustion?
Ans. There are mainly two types of combustion: complete combustion and incomplete combustion. Complete combustion occurs when there is enough oxygen, producing carbon dioxide and water as byproducts. Incomplete combustion happens when there is insufficient oxygen, leading to the formation of carbon monoxide and soot.
3. What are the products of combustion?
Ans. The primary products of combustion are carbon dioxide (CO2) and water (H2O) when the combustion is complete. Incomplete combustion can produce carbon monoxide (CO), soot, and other harmful substances.
4. Why is combustion important in daily life?
Ans. Combustion is essential in daily life as it is the primary method for generating energy. It powers vehicles, heats homes, and is used in cooking. It also plays a significant role in various industrial processes.
5. What are the environmental impacts of combustion?
Ans. Combustion can negatively impact the environment by releasing greenhouse gases like carbon dioxide, contributing to global warming. It can also produce pollutants such as nitrogen oxides and particulate matter, which can harm air quality and human health.
