what is the estimate time of the formation and evolution of the solar system? It began 4.5 billion years ago is there any proof or model which justifies its formation? Yes, it's called the nebular hypothesis who gave this hypothesis? Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace what was stated in it, can you give at least one point? It says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud. what do you mean by this last term of cloud? It is a type of interstellar cloud, the density and size of which permit the formation of molecules, which unexpected chemicals are found in the other type of cloud you mentioned just now? Formaldehyde, methanol, and vinyl alcohol. is the first one used in photography? Yes, in photography, formaldehyde is used in low concentrations for process stabilizer in the final wash step. where else is it used? In drug testing, as an antiperspirant. is the second one toxic? Methanol is toxic and it is used for what? It is used to fuel internal combustion engines. how is this engine lubricated? In 2-stroke crankcase scavenged engines, the interior of the crankcase, and therefore the crankshaft, connecting rod and bottom of the pistons are sprayed by the 2-stroke oil in the air-fuel-oil mixture which is then burned along with the fuel.

Internal combustion engine [SEP] Air pollution
Internal combustion engines such as reciprocating internal combustion engines produce air pollution emissions, due to incomplete combustion of carbonaceous fuel. The main derivatives of the process are carbon dioxide , water and some soot—also called particulate matter (PM). The effects of inhaling particulate matter have been studied in humans and animals and include asthma, lung cancer, cardiovascular issues, and premature death. There are, however, some additional products of the combustion process that include nitrogen oxides and sulfur and some uncombusted hydrocarbons, depending on the operating conditions and the fuel-air ratio. Not all of the fuel is completely consumed by the combustion process.
