Carbon and its important with Diamonds, Graphite And bucky Balls

    
                                                           Carbon and its importance

very small quantities of carbon are found in the earths crust as the free elements. It is present in approximately one million known compounds. one of the unique property of carbon is that is atoms combine with each other to form long ring compounds.          

    Allotropic forms of carbon: 

             Carbon exists in three different forms having different physical properties. When an element is found in more than one physical forms in the same state, it is called allotropy and such physical forms are called allotropic forms Diamond, graphite and bucky balls are the allotropic forms of carbon. These allotropic forms have different physical properties such as appearance and density but they are the elements and have the same chemical properties.

                                                                    

Define :



                                                                              Graphite:

It is a second crystalline form of carbon found in nature or made from coal by heating it in an electric furnace. It is a soft black solid which has shiny and a greasy feeling. It is used for the core of (lead pencil) as a lubricant and in paints.

                                                                              Diamond:

It is a colourless, transparent and crystalline form of carbon. Which is found in the earth under great heat and pressure. It is one of the hardest substance known, hence is used for tipping rock drills, in glass cutting, in polishing other precious stones. 

                                                                             Bucky Balls:

Bucky balls is the third form of pure carbon known to exist naturally. It is used as a semi-conductors and lubricants.

The Similarities and Differences Between the Sun and Moon

  The Similarities and Differences Between the Sun and Moon The sun and the moon are the two most prominent celestial objects in Earth’s sky. They affect the daily lives of people in significant ways but are very different in their characteristics and effects on the solar system and the Earth. Both of these bodies have been the subjects of extensive scientific research, as well as myths and tales across the ages. Measurements of Time Both the sun and the moon serve as bases for systems of time measurement. The moon is the Earth’s only natural satellite and is the basis of the month on modern calendars. The moon takes 27.3 days to fully rotate around the earth. The sun, around which the Earth orbits, is the basis of the calendar year and day. The sun itself rotates within a period of about 25 days. How They Were Formed The moon and sun are both bright round objects in the sky. Indeed, viewed from the Earth's surface, both appear as similarly sized disks. That said, however, they are...

What Are the Two Planets That Don't Get Solar or Lunar Eclipses?

  What Are the Two Planets That Don't Get Solar or Lunar Eclipses? As Earth and the moon revolve around the sun, they periodically align with the sun in such a way that Earth moves into the moon's shadow and vice versa. Known as eclipses, these are spectacular events for observers on Earth. But they cannot occur on Mercury or Venus: Neither planet has a moon. Eclipses on the other planets in our solar system are possible but probably different than those on Earth. Mercury The first planet in the solar system, Mercury, is closer to the sun than Earth by more than half. From Mercury's surface, the sun appears three times as large as it does from Earth. If Mercury had a moon, it would have to be large enough to cover that disk for observers on the planet's surface to experience a solar eclipse. Such a moon, unless it were very close to the planet, would probably have to be larger than Mercury itself. Thirteen times every century, Earth falls into Mercury's shadow as it...

Physical Activity for Adults

Image
                   Physical Activity for Adults Physical activity plays an important role in both physical and mental health. People who are physically active tend to live longer, healthier lives. Active people are more productive, and more likely to avoid illness and injury ¹ . Whether it’s dancing, exploring, sports, or working out at the gym, safe and regular physical activity will keep the body moving and the heart pumping to provide immediate and long-term health benefits. At least a minimum of 30 minutes physical activity a day can: Lower risk of heart disease Lower cholesterol Lower blood pressure Lower risk of Type 2 diabetes Help manage weight Improve endurance, strength, flexibility Build stronger bones, muscles and joints Lower risk of osteoporosis  Reduce risk of falls Boost energy and mood Improve sleep On the other hand, a lack of physical activity can increase risks of developing preventable conditions, such as: Anxi...
