Recycling is processing used materials into new products to prevent waste of potentially useful materials‚ reduce the consumption of fresh raw materials‚ reduce energy usage‚ reduce water and air pollution. Many kinds of glass‚ paper‚ metal‚ plastic‚ textiles and electronics can be recyclable materials. Goverments encourage their citizens to seperate their garbage and they make some rules for restaurants and supermarkets to supply recycling process. Although it is claimed that recycling is not worth

N.S Exam Study Notes • Matter&Material • Matter-everything around you‚ it is anything made of atoms and molecules. It’s anything that has a mass. Matter is related to light and electromagnetic radiation. Usually found in a few forms and it has 5 states- (Solids‚Liquids‚Gases‚Plasmas‚Bose Einstein Condensates) • Mass- It is the amount of material in an object. It is the same on Earth or Mars. It is the amount of matter which an object contains. • Weight- It is how heavy something is. It is a

Engineering Materials Week 2 3.1 What is the difference between atomic structure and crystal structure? Atomic structure relates to the number of protons and neutrons in the nucleus of an atom. Crystal structure pertains to the arrangement of atoms in the crystalline solid material. 3.9 Calculate the radius of a tantalum atom‚ given that Ta has an BCC crystal structure‚ a density of 16.6 g/cm^3‚ and an atomic weight of 180.9 g/mol. For BCC n=2 atoms/unit cell 3.47 Below are shown three different

Waste materials in markets or even in public places continually piled up every other day when it is not fetched by a garbage truck. These waste materials are primarily composed of coconut shells in markets‚ wastepaper in schools and offices‚ rice hulls in agricultural remains and sawdust‚ a waste product produce in the lumber shops. This study was conducted to reduce the percentage breakdown of deforestation which would soon contribute to the prevalent global warming. Since waste materials such as

Assignment On Engineering Materials (Glass) Introduction Glass is a non-crystalline solid material. Glasses are typically brittle‚ and often optically transparent. The most prevalent type of glass‚ used for centuries in windows and drinking vessels‚ is soda-lime glass‚ made of about 75% silica (SiO2) plus Na2O‚ CaO‚ and several minor additives. Often‚ the term glass is used in a restricted sense to refer to this specific use. [pic] [pic]Roman Cage Cup from the 4th century A.D. In

The Effect of the Type of Building Material on the pH of the Vinegar Introduction: For this experiment‚ the town council wanted to test which building material would be the best to build statues in a zoo. The building material with the lowest pH would be the best building material because while 7 is neutral anything below 7 is considered acidic and anything higher than 7 results in a base. Precipitation of 5.5 or lower is considered acid rain. Connecticut and most of the United States have to

comprehension. The listening material may contain a variety of fields in life or society. For instance‚ it is likely a business report‚ a daily conversation or a political issue which confuse the listener. These conversations may include words‚ phrases or terms unfamiliar to listeners. They are totally strange to them so it is such a hard job to listen when the message is full of terminology. The solution is to ask the students to practice as much as they can on these various materials. Therefore‚ they can
