Science Hub: Air and Combustion

This set of vocabulary flashcards covers the fundamental principles of combustion, the composition of air, and renewable energy initiatives in Egypt based on the Science Hub lecture notes.

Air

A mixture of gases in unequal proportions, primarily consisting of Nitrogen, Oxygen, and Carbon dioxide.

Oxygen

A gas that makes up $21\%$ of air; it is necessary for respiration and is the only component of air that supports combustion.

Nitrogen

The largest component of air, making up $78\%$ of the mixture, which does not support combustion.

Carbon dioxide ($CO_2$)

A gas that makes up $0.04\%$ of air and does not support combustion.

Combustion

The process of a material combining with oxygen; it requires fuel, oxygen, and heat to occur and continue.

Fuel

One of the three conditions required for combustion, defined as something that can burn.

Heat

One of the three conditions for combustion, required in a sufficient amount to start a fire.

Benban Solar Station

A clean energy facility located near Aswan that generates electricity from the sun and wind to reduce $CO_2$ and export energy.

Oxygen Gas Collection

A method used for gases not too soluble in water, involving turning a jar filled with water upside down until it is $70\%$ filled with gas.
