Fun Facts

In a dryer, the clothes are mechanically dried up squeezing the clothes to separate from water forcefully, while in hanging, the clothes dry up in a natural way. All the water that drips from the clothes goes to the air, that’s it.

Now just think where all the water goes from billions of clothes dried up daily in the world by hanging them outside under the heat of the sun. Under broad daylight and even if small amount of rays is coming from the sun, all the water become part of the air and go to the atmosphere in a process called evaporation.

When the water goes to the air, it is hidden by the clouds in the sky and the clouds become white, some are gray and others become dark. The clouds are white because they are not yet ripe to fall as rain. Some are gray because they have already formed some droplets of water that are ready to come back to the earth. Others are dark because anytime, they will fall as heavy rains.

These rains form part of the rivers, oceans, lakes and other waterways. Water fall as snow during winter so, it becomes a cycle from the earth and goes back to the earth. The air is saturated in the clouds that it’s hard for it to hold water because of the low temperature. Hence, the droplets of water in the clouds start growing combining with the extra water in the moist air of the clouds.

When these water droplets become so large by constantly hitting each other during a thunderstorm, they are pulled by the gravity of the earth. Still, when they become larger by combining with other droplets, they fall out on the earth as rain.

Supposing a big container filled with water is placed in an open space but the temperature does not change, would the process of evaporation be slower? Humidity depends on the temperature and the air’s vapor pressure controls the process. Proportionality is not regarded as a linear inverse; the density of the air affects the rate of evaporation. This process is decreased slightly when more water vapor goes to the air which also lowers the air temperature.

Therefore, it is safe to assume that the water in a big container placed under constant temperature would evaporate slower than if the temperature is rising or variable. There are several factors that affect evaporation but in reality, only a few major factors will work together to effect the process of evaporation. For example in a field of crops, the soil moisture in the soil will not evaporate quickly even if it is under the heat of the sun if there are large plant canopies that obstruct the process of evaporation.

The process of evaporation is clearly described in equations involving chemical kinetics. It is a competition between the evaporation process whereby water molecules present in the water moves to the liquid phase or what we call the process of condensation. At any kind of temperature, evaporation is proportional to water concentration in the liquid phase if there is an amount of water involved. However, this condition is altered when there is something that is dissolved in water like salt.

Any kind of material which has greater density than water will sink. Oil is lighter than water so, that means any amount of oil will float in water. That means oil cannot sink in water just like a submarine.

The problem is how to make oil dense than water or how to decrease the density of water, to allow the oil to sink.

In this case, you can make use of a kind of oil that has a greater density than water. Some oils may contain suspended solids which can make it heavier than water. Bigger objects with heavier weight will certainly have an increased density preventing them to float in water. In some cases, heat may be applied to let oil sink in water.

When some objects are heated, their density decreases, but the rates vary accordingly. A kind of oil which has a low coefficient of expansion may stay close to its original value when the density of water is reduced in heating. If the low density of water is obtained before it boils, you can be sure that the oil will sink.

If something floats or sinks in water, it has something to do with density. A stone is heavier than a piece of styrofoam of the same size. The density of oil is the same as the styrofoam, and the density of water is like the stone.

In the law of buoyancy, we talk about the buoyancy force that keeps an object float and makes another object sink. Objects that are less dense are moved in upward direction and those that are denser are moved downward. Since oil is on the same feature as a styrofoam that is less dense, oil is therefore moved in an upward direction, while the water which is denser is moved downward.

Therefore, in order to allow the oil to sink in water, you have to make its density greater to the point that it is more dense than water. However, that thing is very difficult to achieve in liquid form because you cannot squeeze it just like a styrofoam which you can smash altogether like a rock to increase its density.

So, to make it possible for the oil to sink, you have to mix it up with something solid. This is the same case with seawater being more dense than fresh water since the weight of the salt adds up to the weight of the water. The only way to make oil sink in water is by pushing the oil into the water with your hands, or mixing it up with another element to make it dense.

In the case of vegetable oil mixed with water, if you shake it up inside a sealed bottle, it appears to be mixed, but actually it does not. They just separate with each other according to density, and the oil will float on top of the water. Anything which is less dense than any fluid will absolutely float on top of it.

Many people will certainly say “enjoy.”  Those who are lovers of the sea will of course appreciate and love this phenomenon.  Can you imagine that you can enjoy staying underwater without any gadgets at all?  You can catch fish as long as you want and enjoy the beautiful scenery down there.

You can take photos anywhere without the fear of suffocation due to loss of breath.  You can even go to far places and even at the deepest part of the ocean without carrying anything with you.  All you need is something that you can use to catch fish.  You can enjoy your favorite water sports anytime of the year without worry on giant waves.  Incredible isn’t it?

There is no problem with storm or any form of weather disturbances when you are in the middle of the ocean because you are not afraid of drowning.  You can perform more than a scuba diver and hey, you can be hired to lead a search and rescue team to save victims of wreckage in the sea.  What more, you can establish a business conglomerate involved in sea rescue business.

You can even search for treasures beneath the sea with your unique ability of staying underwater for so long.  But wait; is this true or just the works of plain imagination?

In the year 2007, a stunning experiment went underway at the Tokyo’s Waseda University by scientists whose primary aim was to produce a perfect system of installing an artificial gill in human beings.  This will enable divers to stay beneath the sea for as long as they want without any breathing apparatus on hand.

The outer layer of the device to be installed is taken from silicon strands which shield a membrane containing hemoglobin solution.  Oxygen is drawn by the liquid thru the inflow of superfluous hydrogen.  When the hemoglobin is heated, it will release its cargo which will pass thru the windpipe of the swimmer by means of a scuba mouthpiece.

Two interested Americans who saw the initial launching of this innovative phenomenon in the TV have already tried the operation in Tokyo.  Their account based on their experience stated that a certain Mr. Mitsubishi is conducting the operation in Tokyo.  If you are serious about the operation, you will be required to sign a bunch of papers concerning the whole procedure, the risks, side effects if any, and refunds if it won’t be successful.  They found out later that indeed, they can stay beneath the water for so long.  The only drawback is that they prefer eating fish all the time.

This scientific procedure is being perfected based on the breathing ability of fish under water.  However, the scientists are faced with the problem on how to extract a sizeable amount of oxygen from the hemoglobin solution.  There is still an ongoing discussions and brainstorming on how to settle this problem.

But scientists consider this as a minor problem and soon, they would be ready to unveil this perfected unique breathing system under the water, in perfect form.  When this is ready, you can stay beneath the sea for hours without fear except for your body’s capacity to endure the cold water down there.
