ICE
What if Ice did not Float?
This is an interesting question that confounded people for many years. In letters between correspondents in different regions of Arabia, the question was bandied, and answered. The thought was that when water froze in a container that it did contract. Thus the void where the water had been formed a vacuum and the heavier air in the outside of the flask caused the water container to implode because of the vacuum that was formed. However, one of the correspondents, the one writing the original query to a more learned colleague, found that the flasks broke out, not in as was indicated in the original explanation. The more experienced of the two did have an explanation of this,
But it is more metaphysical than scientific. He said frozen water creates a space between itself and the container, and that this space...
This fact will allow the company to now grow its operations in the target locations while some competitive companies would have to concentrate on generating more income to cover the financial liabilities, rather than to make more capital expenditure to grow the brand. The company has chosen to reduce the number of its current assets by decreasing the number of inventories which does not have a negative impact on the
Instant Freeze Water Instantly Frozen Water Experiment (Poulter, N.d.) There is a common phenomenon that has been experienced by many people. During the winter, if you leave a bottle of water in a car, garage, or other cold place overnight then something quite interesting can happen -- then the cap is opened, the liquid can freeze instantly. This experiment reproduces this phenomenon using a few simple materials and also explains the science
Seawater and Desalination The seas are made up of water, but that water is not drinkable, requiring treatment in desalination plants prior to distribution in drinking water systems. To understand how and why it is not drinkable, and the complexities of desalination, it is necessary to look at the chemical and physical properties of seawater. Following this, two different desalination methods are discussed. Chemical and Physical Properties of Sea Water Seawater is made
For example, the oceans make it possible for life to exist on earth because they create more moderate temperatures by absorbing large amounts of solar heat (Riley 3). Otherwise, it would become too hot for plants and animals to survive. Water also helps organisms to regulate their internal body temperatures (Pidwirny 1). Water has an extremely high surface tension. Riley defines surface tension as being "the attractive force exerted by
A recent study though, suggests that over five thousand years ago, the Arctic had considerably less sea ice in the summertime than today, but it was not apparent whether the Arctic was totally free of sea ice in the summertime throughout that time. 8) What is the difference between the seasonal patterns of Arctic Ice in comparison to Antarctic Ice? The model of Antarctic maximum sea ice is generally symmetric around
Leadership Discussions First Half Conflicting Obligations Identify at least two ethical dilemmas that occur when you are in a position of leadership. What makes the dilemmas ethical? Would you expect each person to react to the dilemma in the same way? People have different ways of reacting to dilemmas. In my position as a leader, I have encountered a situation where I had to choose tow rights. In this case, I was entangled
