What are some examples of petrochemicals?

Primary petrochemicals go through chemical processes to make more complicated organic chemicals that go into producing various items. Methanol converts to formaldehyde and acetic acid, which go into making plastics, fibers, adhesives and paper products. Ethylene makes ethanol, polyethylene resins, ethylene oxide and ethylbenzene. These ethylene-based petrochemicals produce items such as plastics, coolants, pharmaceuticals and cosmetics. Propylene makes Styrofoam, butadiene contributes to synthetic rubber, and benzene produces the synthetic fiber nylon.\nThe most important process with regards ..

What is the densest material on Earth?

Scientists first created quark-glucon plasma in February 2010 by colliding gold and lead ions with each other at speeds nearing the speed of light. The result was a plasma so dense that just 1 cubic centimeter weighs over 40 billion tons. This state of matter only exists in temperatures above 4 trillion degrees Celsius. Scientists theorize that the universe was filled with quark-glucon plasma one-trillionth of a second after the big bang.

What are the properties of aluminum?

Aluminum is a Period 3 metal that exists as a solid at room temperature. The element is atomic number 13, with an atomic mass of 26.98. Aluminum's melting point is 1,220 degrees Fahrenheit, and its boiling point is 4,566 degrees Fahrenheit. In its solid phase, aluminum has a density of 2.7 grams per cubic centimeter, though its low density does not significantly impact its strength.\nUnlike steel alloys, aluminum does not become brittle at low temperatures. Instead, pure aluminum and many of its alloys become stronger at low temperatures. At temperatures over 212 degrees Fahrenheit, alumi..

What is a moringa plant?

Moringa is also used in the production of food and hair care products. It is notable that the supplement is considered unsafe to ingest during pregnancy. After the manufacturing process, the leftover pulp from the plant is used as a fertilizer. Additionally, it is used to purify well water. Cultivation of moringa is typically inexpensive, making it readily available to the general public.

Why do babies have more bones than adults?

HowStuffWorks indicates that the skull is one example of a bone that grows together. At birth, the skull is in three fragments, so the head is able to fit through the birth canal. The sections of the skull eventually come together into one solid bone.\nSome bones, such as kneecaps, begin as cartilage in babies, explains HowStuffWorks. The cartilage "ossifies," which means it slowly turns into bone. Cells called "osteoblasts" produce bone matter that covers the cartilage, and blood vessels form to spread nutrients throughout the new bone.

What are some interesting earthquake facts for kids?

Seismologists give earthquakes different magnitude rankings depending on their severity. A magnitude three earthquake is fairly unnoticeable and not likely to be felt. On the other hand, a magnitude six earthquake is likely to cause quite a bit of damage. As of 2014, the most powerful earthquake ever measured occurred in Chile in 1960 when a 9.5 magnitude earthquake struck the city of Valdivia.\nThe damage caused by earthquakes can be exacerbated when they occur in areas close to water. In March 2011, an earthquake in Japan measured at 9.0 on the Richter scale and caused the deaths of more tha..

What color do you get when you mix red and blue together?

Red and blue are both primary colors. This means that they cannot be made by mixing other colors together. When two primary colors are mixed together, the new color is called a secondary color, and varying shades can be produced depending on the amount of each primary color in the mix. All secondary colors are placed on the color wheel between the colors that were mixed to create them.

What is human environment interaction?

Human environment interaction is an overarching theme in the study of geography that concerns the many relationships, both positive and negative, between people and their surroundings. This examination includes how people depend on and modify the environment and how people adapt behaviorally and physically in response to the environment. The study of human environment interaction focuses more on groups of people or cultures rather than on individuals. Therefore, human environment interaction looks at the interplay between human social systems and larger ecosystems.\nAn illustration of human en..

Which elements are chemically unreactive?

Just as the ability to react makes some elements suited for certain purposes, lack of excitability makes noble gases ideal for specific applications. These elements are used primarily in balloons, light bulbs and advertising signs. When added to balloons and airships, noble gases make air less dense, which enables balloons and spacecraft to move upwards. The noble gas called argon is used primarily to generate light in light bulbs. Bulbs contain thin metal filaments, which would corrode and fade upon interacting with oxygen in the absence of argon. The unreactive nature of argon makes it ideal..
