PETROLEUM PRODUCT

Petroleum products, such as gasoline, kerosene, home heating oil, residual fuel oil and lubricating oils, come from one source - crude oil found below the earth’s surface, as well as under large bodies of water, from a few hundred feet below the surface to as deep as 25,000 feet into the earth’s interior. Sometimes crude oil is secured by drilling a hole through the earth, but more dry holes are drilled than those producing oil. Pressure at the source or pumping forces crude oil to the surface.

Crude oil welts flow at varying rates, from ten to thousands of barrels per hour. Petroleum products vary greatly in physical appearance: thin, thick, transparent, or opaque. Their chemical composition is made up of only two elements: carbon and hydrogen, which form compounds called hydrocarbons. Other chemical elements found in union with the hydrocarbons are few and are classified as impurities. Trace elements are also found, but these are of such minute quantities that they are disregarded. The combination of carbon and hydrogen forms many thousands of compounds, which are possible because of the various positions, and varied joining of these two atoms in the hydrocarbon molecule.

The various petroleum products are refined from the crude oil by heating and condensing the vapours. These products are the so-chatted tight oils, such as gasoline, kerosene and distillate oil. The residue remaining after the tight oils are distilled is known as heavy or residual fuel oil and is used mostly for burning under boilers. Additional complicated refining processes rearrange the chemical structure of the hydrocarbons to produce other products, some of which are used to upgrade and increase the octane rating of various types of gasoline.

HOW TO MAKE CHOCOLATE

Have you ever wondered how people get chocolate from? In this article we'll enter the amazing world of chocolate so you can understand exactly what you're eating.

Chocolate starts with a tree called the cacao tree. This tree grows in equatorial regions, especially in places such as South America, Africa, and Indonesia. The cacao tree produces a fruit about the size of a small pine apple. Inside the fruit are the tree's seeds, also known as cocoa beans.

The beans are fermented for about a week, dried in the sun and then shipped to the chocolate maker. The chocolate maker starts by roasting the beans to bring out the flavour. Different beans from different places have different qualities and flavor, so they are often sorted and blended to produce a distinctive mix. Next, the roasted beans are winnowed. Winnowing removes the meat nib of the cacao bean from its shell. Then, the nibs are blended. The blended nibs are ground to make it a liquid. The liquid is called chocolate liquor. It tastes bitter. All seeds contain some amount of fat, and cacao beans are not different. However, cacao beans are half fat, which is why the ground nibs form liquid. It's pure bitter chocolate.

A. removes the meat nib of the cacao bean from its shell

How Does Tornado Form ?

Tornado is the most damaging storm.The word tornado come from Spanish “Tronada” that mean thunder storm. Also come from Latin language ”Tonare” which mean rumbling. According to the story,the word tornado was taken from combination between ronada and Tornar in Spanish. Tornado is air column which rotate very fast and form relation between cumulonimbus cloud. Usually tornado has wind velocity between 177 km/hours or more with reach average 75 meters and attack several kilometers before disappearing. Several tornado which reach wind velocity more than 300-480 km/hours have wide more than one mile and can survive in the surface more than 100 km.

Tornado generally happens in the afternoon to evening. In America, tornado happens between 15.00-21.00. Although tornado has been research by the scientist, in every continent, most of tornado happens in America. In America, most of tornado happen in tornado alley in middle-west America. Other area which generally happen tornado are South Canada, South Africa, East and south Asia, Middle Europe, Italy, West Australia, New South Wales, and Indonesia. In Indonesia, usually happen in Sumatra and Java.

Tornado has some types. They are weak, strong and violence tornado. Weak tornado include 88% of all tornado. The wind velocity is less than 112 mph. Weak tornado happen about 1-10 minutes. Death because of this tornado are about 5% of the total death because of tornado. Strong tornado include 11% of all tornado. The wind velocity is between113-206 mph.This tornado happens in 20 minutes or more. The death because of strong tornado is about 30% of the total death because of tornado. Violent tornado is rarely happen. This include 1% of all tornado. The wind velocity is more than 205 mph or more. This tornado happens in one hours or more. Although rarely happen, this tornado can cause death about 70% of the total death because of tornado.

Before tornado happens, it has several signal. First, the sky seems dark. Then happen ice rain around the area, usually 20-25 minutes. After that, the situation will calm, but the sky become darker. Fourth, cloud moving around the area. Fifth, the sound of tornado heard. At the beginning, the sound like water fall, but in the process of time it will change until like jet plane which is very loud. A tornado usually move from southwest to north east.
The change of air layer is the cause of tornado. In this case, if the cold air layer is above the hot air layer, the hot air layer go up with velocity about 300 km/hour. The air which infiltrating from this side, cause wind rotate and form Tornado.
