PETROLEUM (पेट्रोलियम) Petrol At some places in nature, a thick, viscous and dark colored liquid is found under the rock, which mainly contains aliphatic hydrocarbons up to C 1 to C 40 , this fluid is called refined oil or petroleum. The word petroleum is derived from the Latin words petra and olium which is found under rocks within the earth, hence it is also called mineral oil. Within the earth, this fluid floats above the salt solution. A gas atmosphere exists along with the floating petroleum inside the Earth, which is called natural gas. Petroleum is also called liquid gold. In the present era, this fluid is more valuable than gold for any nation. The progress of any nation depends to a large extent on how much petroleum it has. Its use is very important in various tasks like agricultural industry, traffic communication etc. This oil is found in the highest amount in the United States. Russia Venezuela is also found in greater quantities in Mexico, Burma etc. ...
Canal Rays and Discovery of Proton कैनाल किरणें और प्रोटॉन की खोज Canal Rays and Discovery of Proton G oldstein (1886) made it known that when light is immersed in gases on a low pressure in the immersion tube, which is perforated cathode, light comes out behind the cathode. They proved by experiment that a type of ray emitted from the cathode cavity and entering the area behind the cathode, there is a brightness behind the cathode. Goldstein named the rays of canal rays, because these rays emitted from cathode pores and moved on the other side. Canal Rays: The use of wine (1897) proved that the canal rays are made of concentrated particles. JJ Thomson named these rays 'Dhan Rays' because these rays are made of corona particles. Properties of wealth rays (1) Canal rays move in ...
