NITROGEN IS MORE IMPORTANT THAN YOU THINK INTRODUCTION: In this article, we discuss nitrogen its important properties, and some incidents that happened in the past with people and instruments that deal with nitrogen. So, let's start: LIQUID NITROGEN INCIDENT THAT KILLED THREE TECHNICIAN OF NASA: The First space shuttle mission was named STS-1, the first orbital mission of NASA. This mission is uniquely described in this article due to the incident in which three technicians died due to inhalation of excess nitrogen of nitrogen. IMPORTANCE OF NITROGEN: Nitrogen is a crucial element in the periodic table due to many important properties. Nitrogen is a non-toxic & colorless gas that occupies 78% of the atmosphere. HISTORY OF NITROGEN: In the past, scientists had different opinions about this gas. For example, some scientists think it was brunt air because no combination occur in the presence of this element. Some believe it is very toxic and has no life because the environment fil...
Properties of Most Important Things of Our Daily Life: Mechanical Properties of Materials Introduction to Mechanical Properties of Materials: Materials that play an important role in everyday life. Imagine building without steel, cars without grey cast iron engines, and airplanes without titanium-aluminum alloys. Well, Imagine this kind of thing is hard because without this there are no machines, no electrical appliances, and no computers. Well, you know understand why materials are so important for us. Here in this article, we are talking about some mechanical properties of materials. Mechanical properties of materials: In this article, we discuss mechanical properties which are as follows: 1. Stiffness: Stiffness is the ability of materials which cause resistance to elastic deformation. Well, after reading that you thought that it must break easily. But stiffness doesn't mean that it means it is hard to cause elastic deformation in that material. For example, there is a rod of s...
