Açıklama
Nitrogen prevents food from degrading by creating an unreactive atmosphere.
Aluminium is used in buildings because it's resistant to corrosion and thermally efficient.
Copper is a versatile metal used in many applications, including electrical wiring, plumbing, construction, and transportation.
Sulphur is commonly used as an ingredient in the head of a match, contributing to its ability to ignite easily when struck against a striking surface; most modern safety matches contain sulfur or charcoal alongside other chemicals like potassium chlorate and antimony sulphide. Sulphur acts as a fuel in the match head, readily combusting when combined with an oxidizer like potassium chlorate.
