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.
As a result of the Industrial Revolution, cotton became the worldâs most important non-food agricultural product-- and it remains so to this day. In the 1700s, cotton textiles had many production advantages over other types of cloth.The first textile factory in Great Britain was actually for making silk.orld Trade gradually increased in the centuries before the Industrial Revolution and provided European countries access to raw materials and a market for goods. It also increased wealth that could then be loaned by banks to finance more industrial expansion in an upward spiral of economic growth.
