OK . . .What does a 5W-30 do that an SAE 30 won't? When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. The numbers without the W are all tested at 210Â° F or 100Â° C which is considered an approximation of engine operating temperature.
(Answer #1). The Industrial Revolution was a time when the world's economy started to be more industrialized -- things came to be made in factories rather than by individual artisans. Great Britain took the lead in this largely because of geography.y about mid nineteenth century it took firm roots in western Europe and northeastern USA. The industrial revolution first developed in Great Britain for several reasons. The two most important of these are abundant supply of coal and iron and the economic advantages accruing to the country because of its colony.
The United Kingdom, where the industrial revolution began in the late 18th century, has a long history of manufacturing, which contributed to Britain's early economic growth.he growth was driven by international trading relationships Britain developed with Asia, Europe and the Americas, as well as entrepreneurialism, work ethic and the availability of natural resources such as coal.
