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...
Mysterious Things About Gravitational Force Introduction: Science is the best way to learn about this nature. Humans are very curious that's why humans started to learn about nature as time passed our understanding of nature increased to deal with such a huge amount of knowledge we divided them into different branches like biology, chemistry, and physics. Gravitational force is fundamental, so knowing about it is extremely important. That's why understanding about them is very important. So in this article, we are talking about what is gravity? And how it is the biggest mystery to scientists. This mystery is so complicated that instead of been solve it has become more complicated with time. Gravity According to Newton: Gravity was the first fundamental force known to humans by the brilliant scientist "Sir Issac Newton". He says that two objects having mass attract each other with a force known as Gravitational Force which is directly proportional to the product of the...
