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...
Black Body Radiation: A Phenomena which change physics forever Introduction: In the beginning, classical physics was able to predict everything accurately and we are heavily dependent on it for everything. But it said that nothing is perfect. Likewise, the case of classical physics which fails to explain certain phenomena. The one such case that classical physics can't explain is "BLACK BODY RADIATION " . It is said that everybody emits electromagnetic radiation above absolute zero. But scientists are very curious. They try to imagine a body that emits every wavelength of electromagnetic radiation or absorbs every kind of wavelength. This body was called "BLACK BODY". Point to be noted: There is one point that you must keep in mind: 1. In this universe no perfect black body is present. Example: Let's imagine a bulb with a platinum filament if we increase the voltage temperature of the filament increase and when the temperature of the filament reaches 500 de...
