Yes. Carbon is added to iron in steel to make the steel stronger by making it more rigid. The more rigid a metal is, the less malleable it is.

Freezing water of is an example of physical change.

It won't work. The slip rings work in conjunction with the brushes to connect a rotating part of the unit with the stationary part. We need to couple current into and out of the rotor, and without the slip rings for the brushes to ride on, we can't do that, and the motor won't work.

A glass-lined reactor typically consists of a metal vessel, often made of carbon steel or stainless steel, that is coated with a layer of glass. This glass lining provides excellent resistance to corrosion and chemical attack, making it ideal for reactions involving aggressive substances. The glass is usually fused to the metal at high temperatures to create a durable, inert surface that can withstand high pressures and temperatures. The composition of the glass itself often includes silica, alumina, and other oxides to enhance its thermal and chemical stability.

Yes, there is demand for chemical engg. if he is good at thermodynamics. reaction engineering and kinetics and process calculation... a chemical engg without these subject is nothing but a coolie...

A fraction in chemistry is a quantity collected from a sample or batch of a substance during fractional distillation i.e. where a mixture is separated into different parts called fractions. A fraction can be defined as a group of chemicals that have similar boiling points.

Chemical engineers produce a huge variety of products and here are just a small sample of the list that a chemical engineer can produce:

1. Oil and gas products (gasoline, engine oil, organic solvents, etc.)

2. Food

3. Medicine

4. Plastics

5. Metals from ore refining and metallurgy

6. Inorganic solvents

7. ...and so much more!

The list goes on and on but chemical engineers are involved in many facets of society and the products we produce can be found just about anywhere.

It is 1.07 gm/cc for amorphous type..

and 1.25 gm/cc for crystalline.

Basicaly chlorhexidine is an antibacterial used as a disinfectant and other applications. It is also used in disinfectants (disinfection of the skin and hands). Chlorhexidine is often used as an active ingredient in mouthwash designed to reduce dental plaque and oral bacteria.

Chlorhexidine lasts longer in the mouth than other mouthwashes, which is partly why it is to be preferred over other treatments for gums. So that is the reason for chlorhexidine to be used in tootpast and mouthwash.

Engr., Felix Maramba- his work included researcehes on indigenous sources of energy like biogas, biofuel

The raw material used for manufacture of cement are limestone and clay. They are ground to form very fine powder and then converted to slurry. The slurry is baked at very high temperature to form granular mass called kilnker. The kilnker is ground and mixed with powdered gypsum to form cement.

no resin, just reversed osmosisto get purest type of water,

wayer purification can be done in a water purification plant, which involves mechanical, biological and chemical cleaning of the water and bringing it up to international standards

You want a liquid that is not compressible so polar compounds are preferres. For safety, the nontoxic and highly stable silicones are used. They have low vapor pressures and high boiling points so they remain liquid and are quite noncompressible.

This type of thermostat is filled with Alcohol, which responds well to changes in airconditioned space.

JP-8 is a fuel specified by the United States Air Force in MIL-DTL-83133E that boil in the range of 186°C (10% boiling point) to 300°C (final boiling point) using the ASTM D2887 test method. The density of JP-8 ranges from 0.775-0.840 kg/L.

advantage: not very good bad to enviroment farting will help break down poo

It is mostly carbon monoxide and nitrogen gases which has some heating value. So it is typically recovered and mixed with natural gas, &/or coke oven gas and used in boilers for steam or other steel heating furnaces for further processing of steel.

Rubber is light,smooth and rubbery.

water can cut through glass but only when at a very high speed and a thin stream

Many of the calculations done by a working ChE involve Thermodynamics, Physical Chemistry and Kinetics and Catalysis. It's not just adding and subtracting by any means. A firm background in Math is required.

I suggest that you find a copy of Perry's Chemical Engineering Handbook in the library, and thumb through it. You will get an feel for some of the work done.

energy is economised since the evaporator at alower pressure heats the following effect

Most ink is a simple suspension of pigments or dyes in water, though much more complex variations exist.

Most modern forms of ink are not significantly affected by moderate changes in temperature, but there are a few effects possible to varying degrees depending on the particular ink.

Like all fluids, a decrease in temperature increases viscosity, affecting the flow of ink.

An extreme decrease in temperature will, of course, freeze the ink.

Extremely high temperature will, of course, vaporize ink.

Low, or freezing temperatures as well as high temperatures can result in altering properties of the suspended particulates causing them to precipitate out and making the remaining dissolved or suspended particles less effective as coloring agents.

It is unlikely that increases in temperature, below boiling, will induce chemical changes beyond those affecting solubility mentioned above, but this may be a rare event in some specialized formulations.

There are many dyes that are affected by age, light, oxygen and temperature and are therefore inappropriate for use as ink, but that does not mean that such deficiencies are always properly avoided by all manufacturers.

Because they can be colored, molded, cured and have reasonably good mechanical properties.
