It classifies pollutants based on different criteria and explains the type of hazard that they cause.

The video discusses the conservation of mass in chemical reactions and the application of this principle in calculating the mass of reactants and products. It also explores the features of chemical equations such as balancing and state...

Global warning is probably the biggest threat facing humanity. If all else fails, could climate-controlling technology be the answer?

This nugget explains pollution of the layers surrounding the earth, air pollutants, global warming and green house effect, acid rain, ozone hole, photochemical smog.

The video discusses atmospheric pollution and the effects of burning fossil fuels. It explains the pollutants created through combustion, such as carbon dioxide, particulates, carbon monoxide, sulfur dioxide, and nitrogen oxides. The...

NASA is sending two missions to Venus this decade and participating in a European Space Agency mission there, too. Lori Glaze, director of planetary science at NASA, discusses these missions and why she’s so excited about what we’re...

We follow Clive Oppenheimer, a volcanologist working on some of the latest techniques to help monitor and predict volcanic eruptions. Volcanic eruptions pose a real threat to communities living nearby and at their most violent they have...

It explains the process of catalysis. It describes the homogeneous and heterogeneous catalysis. It discusses the adsorption theory of heterogeneous catalysis.

This video is a lecture presentation on the contact process, which explains the chemical processes involved in the production of sulfuric acid and the physical conditions required to make those processes as efficient as possible. The...

The video explains how the combustion of fuels produces atmospheric pollutants, such as greenhouse gases, carbon monoxide, carbon particulates, sulfur dioxide, and nitrogen oxides. It describes the chemical reactions that occur during...

Kilauea is an active volcano in Hawaii that erupts every 10 to 20 years. In 2018, Kilauea eruptions on a rift zone destroyed more than 700 hundred homes, forced evacuations, and sent lava downhill to cover 14 square miles of land in...

Dr. Bryan N. Duncan is a deputy project scientist for the Aura Mission at NASA's Goddard Space Flight Center in Greenbelt, Maryland.



He recently presented the story of air quality in three cities: Beijing, Los Angeles...

This program covers part 2 of the very important topic of the atomic theory of matter. We discuss how atoms combine together to form new compounds. Students review the law of conservation of mass and how the mass of the substances at the...

Learn the basics about Reactions of copper. What does copper react to? How is the chemical reaction of copper noticed? Find out more in this video!

Volcano eruptions can wreak havoc on airplanes that fly through the clouds of ash and sulfur dioxide. The ash, in particular, can destroy a jet engine and even cause it to fail mid-flight. However, it can be difficult to detect the...

NASA Goddard Space Flight Center scientist Andrew Sayer talks about how emissions from volcanoes can affect clouds. This video provides an overview of research published in the Journal of Atmospheric Chemistry and Physics. Research:...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

It describes the two steps of extraction- conversion of oxide and reduction of oxide to metal.

This video is a lecture presentation that focuses on atmospheric pollution, discussing the effects of different types of pollution on the environment and living organisms. The lecturer covers the biological consequences of pollution...
