A serious issue this time



Every time i write a post on this blog of mine,i try to bring out a light issue out of my life here at BIET jHANSI or sometimes society at large  but there's a lot of heavy stuff going on in the world right now. So instead of the usual, I'd like to tell you just a little bit about why putting even a little bit of oil in the oceans can be so disastrous.

Most of you know that if you take pretty much any type of oil, it will float on top of water.

 But what if the amount of water you have is much, much larger than the amount of oil that you have? It turns out that the oil will spread out over the surface as much as possible,like try it yourself==while eating food in mess try putting some (some means some...just  much less then a drop)ok....try putting some oil from your vegetable that you are eating(waise bhi panchwati main mess wale itta tel dal dete hain ki bas poocho hi mat)....so what i was saying is that try putting some oil into the jug of water ......and then seee fr urself the area that that minute amount (less then a drop)of oil covers on the surface of water in the jug !

So now,one big question strikes my mind !




How much is as much as possible? ...the answer is==Until the oil on the surface of the water is just one molecule thick. So, how thick is one molecule of oil? Believe it or not, Ben Franklin was the first person to measure it, and you can measure it, too! All you need is some oil, an eyedropper, and a flat, clean body of water.(now don't try it in your mess....especially these notorious SAKETians)


The eyedropper is great, because a single drop of anything that comes out of an eyedropper is going to be almost exactly one milliliter of volume, or one cubic millimeter. That's tiny, isn't it? You'd have to line up one thousand drops in a line to get something one meter (a little over three feet) long. But when you drop just a single drop into a flat pool of water, it spreads out to make a circle that's huge!


This single drop, which was just a millimeter in size (about 1/25th of an inch), now spreads out to a diameter of 24 feet, or over seven meters!


If I work out my math, that means a single molecule of oil is only about 2 nanometers (or 20 Angstroms) thick!

(Beware of the number one hit on google, which unwittingly uses far less than a milliliter of water in their experiment, and gets an answer that's almost 50 times too large!.....here's the link check it out urself...http://www.worsleyschool.net/science/files/molecular/thickness.html)

Well, what does that mean if -- instead of a drop of oil -- I dump an entire gallon of oil into a large body of water?



It would spread out to make a circle that was 450 meters in diameter. That's over a quarter of a mile. From just one gallon (about 3.8 liters).


And what about the Oil Leak which is spilling oil into the gulf of Mexico in the western duniya of ours right now?


It's currently spilling an estimated 200,000 gallons of oil into the gulf of Mexico every day.

In other words, every day, a new 125,000 square kilometers (or 50,000 square miles) of ocean will eventually get coated in oil when it finishes spreading out. That's almost as big as the New York State of America.

Practically, of course, this much oil won't spread out to be one molecule thick; more like 100 molecules thick in most places, but that's still a huge disaster! Many of you will remember the Exxon Valdez spill and the consequences this caused:



Well, the one in the Gulf of Mexico, as I write this, is only seventeen miles away from the Mississippi Delta. It's one thing to look at pictures of animals killed from an oil spill.



This isn't only about animals this time. This isn't happening in a corner of the world where very few people live. This is happening in a place that will affect millions of people. And by time this leak is fixed, we may well exceed the total volume dumped by the 1989 spill(i hope someone at BIET Jhansi remembers that date still !). This is about your world, your oceans, your environment and for many of you, your own health.


Wake up guys !!!!!!!!!!!!!
