The effect of salt temperature on ice - Essay Example These bonds hold the molecules together forming the solid ice (Churchill et al). The salt ions dissolved alter the existing hydrogen bonding in the solid ice and this has an effect on the normal freezing point of the ice causing the temperatures to drop. In this experiment we are going to determine the effect of salt on the temperature of ice. In the first bowl, when the salt is added on the ice, at first nothing happens but after sometime, the temperature of the ice drops before the ice starts melting. The ice the melts gradually and the temperature increases. In the second bowl, the ice starts melting at 0oC a.nd melts gradually as temperatures increases. When salt is added to ice, it is able to lower the freezing point of any water molecules that are on the surface of the ice and this prevents it from freezing again hence helping to melt the ice surrounding the solid ice. Water that is pure in nature has its freezing point fixed at 0oC while salt is able to melt down ice to a temperature of about

Yet it was not a pure Islam, but an Islam mixed with local customs. Another issue that impacted Islam in Central Asia was the Soviet occupation.

The Soviets, in contrast, launched a full-scale assault on Islamic institutions and practices in the mid-1920s, a campaign that intensified dramatically during Stalin’s â€Å"revolution from above† and the purges of the late 1920s and 1930s. Although oppression is not favorable, the result was positive. Due to the oppression, Central Asia has formed its own brand of Islam. While it might be repressive to some, the Islam in Central Asia is not as threatening as in neighboring Afghanistan. Plus, Central Asia has formed their religion and culture in the meantime. It is much better than having another occupation. The announced goals of the new university vividly portray a state vision of Islam that intersects both with issues of nation-building in Central Asia and with a larger global Muslim discourse about the nature of Islam itself. (Damrel) mazhab), one of the four main branches of Sunni Islam (the other three being the Shafi’, Hanbali’i, and Maliki’i mazhabs). The standard argument is that Sunni Islam ultimately prevailed over Shia Islam in the region because it was better able to accommodate local practices and traditions, including eventually Sufism, a mystical and popularized form of Islamic worship that is very open to
