As rubber band is made up from rubber, it possess properties of rubber.

main property of rubber is "ELASTICITY" i.e. whenever you stretched rubber or rubber band it gets stretched & when you released it, it will gain it's original size & shape again.

A promising polymer that could be grown sustainably and that could possibly replace typical plastic is cellulose. Cellulose is a organic polymer produced within plants and there is research in developing some stable products from this resource; however, a lot of research still needs to be done within this area.

Some methods of trapping carbon dioxide are: electrochemical reduction, cooling it into a liquid, and passing the gas through an alkali.

Brine plant will gives us the temparature below zero degrees. but where as in chilled plant the temparature above zero only

The best way to make a fire burn hotter is to use the hottest burning logs that you can. Oak, Ash and Black Locust burn very hot. Feed them into the fire along with fast burning wood such as Maple to keep the fire raging. If you do not burn a fast burning wood with the Oak and Ash, they will burn very hot, but very slowly. The object is to make as many red hot coals from the Oak and Ash at the base of the fire as possible. That is where the heat from your fire will come from and the more coals the hotter the fire will feel. Additional information for those seeking info on other than fireplace fires It also helps to make a low side base surrounded by something and make it narrow at the top, so that all the fire is more focused in one spot. using all these ideas was what made the first copper, silver, and gold things. you may ask yourself how can you make a fire so hot that it burns metal but not whats surrounding it. rocks, carefully build rock kilns.

That depends on the exact circumstances. For example, in electrical circuits, power = I2R. However, since the current, in turn, depends on the voltage and the resistance, it is better to express this as V2/R. For mechanical energy, power is basically speed times force.

The main difference is specilization. I am a chemical engineer myself, and we have the option of specializing in a wide variety of degrees, such as genetic engineering. Note that chemical engineering is a very broad field dealing with polymers, metallurgy, biology, environmental chemistry, and the list goes on. Genetic engineering, in short, is really a specialization of chemical engineering to specifically biological chemistry.

It depends at what temperature. If we assume that it is at its boiling point already, then you do the equation. Q=MH(f). Q= heat, m=mass, and H is the feat of fusion. For water it is 2260J/g. So do it like this. Q=1000mL * 2260J/g. You need 2260 kJ to heat 1L of water at its boiling point.

you take pipes from the fire to the chest and melt ice over it the cold water will keep it cooled down dawg. Fo Sheezy. you take pipes from the fire to the chest and melt ice over it the cold water will keep it cooled down dawg. Fo Sheezy.

When a cold object and a hot object are in direct contact (touching) heat will be transferred through thermal conduction.

Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection.

Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules. Because temperature is directly proportional to kinetic energy, interactions between neighboring particles exchange energy and that exchange energy gradually works it way from the higher temperature regions to the lower temperature regions. The process of the temperature becoming the same is called thermal equilibration.

Convective heat transfer occurs in fluids. If a gas, liquid, or other fluid, changes in fluid density change the buoyancy and will cause fluid to flow (a process called convection) and the heat contained in the warmer fluid is transferred to a new location by the physical movement of the fluid.

Radiative transfer occurs when a hot object radiates electromagnetic energy. While the sun is an obvious source of electromagnetic energy, it is also generated in smaller amounts by any object. The hotter objects radiate more electromagnetic energy and the cooler objects absorb it. This radiative transfer is important but not as noticeable usually as the other two. It does occur between objects whether they are in direct contact or not, but is usually so small as not to be important of the objects are touching.

HYDROGEN & He cant be liuefied because their atomic Masses are small .

second reason is that intramolecular forces are not present in helium and they cannot form covalentbond London forces are weak then inter molecular forces so less energy is required to overcome these forces and gas cannot be cooled.

The preparation of uranium from ores is a long chain of chemical and physical processes.

Kevlar is a synthetic fiber with an extremely high tensile strength. It was created in 1971 by DuPont Chemical group.

The year when the average cost of a barrel of crude oil was $38.00 was 2004. That year, the average price per barrel was $37.66. The average cost for a gallon of regular gasoline in 2004 was: $1.88 per gallon.

Too many places to name, but depends on your specialization. Possible work places are: - Pharmaceuticals - Polymer processing - Gas/oil industry - Nuclear plants - Etc., etc., etc. Chemical engineering is a very broad field with several specializations fitting to many a variety of work places.

Silt

Free-flowing means that something can flow without hindrance. A example of this is a river that exists without being blocked or impeded by a dam. A dam would resist the flow of a river, causing water to remain in or accumulate in a given region, which would not be a free-flowing scenario.

Alkaline hydrolysis is the use of alkali chemical to break down complex molecules (specifically, tissues) into their basic building blocks. Tissue digestion by alkaline hydrolysis is commonly used to dispose of laboratory or veterinary carcasses. It often includes the use of temperature or high pressure, or both. If you put three cows into a tissue digester with alkali (NaOH or KOH, for example), after 20 hours or so you are left with a fluid consisting of amino acids, small peptides, sugars, nutrients, soap, and possibly some minor bone residues. Infectious disease is emiminated, and it is very likely that prions are destroyed as well. If KOH is used in digestion, then in it can be spread as a manure-like fertilizer (in some states which have approved this method). This technology has just recently become affordable, and I imagine you'll be seeing them in farms, co-ops, and meat-packing plants soon, as opposed to major-operation laboratories and veterinary hospitals. Very cool for our struggling environment! Hope this helps!
