If water of different densities come in contact what will happen?
When water of different densities come in contact, they do not mix instantly due to the difference in densities. Instead, they form distinct layers with the denser water sinking below the less dense water. Over time, small-scale mixing processes may occur to eventually achieve equilibrium.
What causes an alkali metal to move over the surface of water while reacting with it?
The densities of lithium, sodium and potassium are less than that of water and so they float on water. They react with water to produce hydrogen gas and this propels the metal across the surface of the water.
Does the water cycle occur all over the world?
Yes, the water cycle occurs all over the world.
How many people die of dirty water each year in Africa?
Water needs to be cleaned by filtering systems. Many people around the world do not have filtering systems near them. They live in poor countries with governments who do not have money to build water systems that cleans the drinking water and provides sewage systems. Believe it or not over 2/3 of the world is like this. We who live in the United States and other parts of the advanced Western World fail to understand this. There are foundations that are trying to get well systems with filtering systems for the poorer nations and places. They are also trying to introduce more sanitary waste systems to them too. A lot of the rivers and lakes in the world are polluted too. So the people get sick from their water sources. Without large water cleaning systems being available to them they simply use the bad water. Boiling water does not always remove the bacteria, metals and other pollutants.
Could machines take over the world if they were programmed to control missile defence systems?
no they couldn`t take over the world but they could blow it up
What was the origin of conveying systems?
The first conveying systems were developed to draw water from wells in the ground. This method was used in various applications over the centuries.
Why do animals fight over water?
Animals fight over water because if none of them had water they world die (thinking of themselves)
Do all heavy objects have high densities?
Not necessarily. Density is determined by the mass of an object relative to its volume. While many heavy objects have high densities, it is possible for a heavy object to have a low density if it is spread out over a large volume.
Where can I look for reviews on hydration systems?
I would look at www.runnersworld.com. They have tested the latest in hydration systems, from tiny handheld water bottles to mega over-the-shoulder packs that carry two liters of water and all your gear.
Why do all conjugated pi systems lower in potential energy when they are planar?
Conjugated pi systems have delocalized electrons which have lower energy when they are spread out over a larger area. In a planar conformation, these electrons can be more evenly distributed along the system, leading to lower potential energy compared to when the system is non-planar with more localized electron densities.
What is density gradient?
Density gradient refers to a gradual change in density of a substance over a distance or volume. It is commonly used in biology and chemistry to separate different components of a mixture based on their densities. By layering liquids of different densities, such as sucrose solutions, a gradient is created that allows particles to move through at different rates based on their densities.
What happens when a mixture of oil and water are left to stand?
Over time, the oil and water in the mixture will separate due to their different densities. Oil, being less dense than water, will float on top while water will settle at the bottom. This is because oil and water do not mix due to their differing chemical properties.
