The adverse effects of particulates on materials include damages to electronic equipment through chemical or mechanical action on electrical contacts, erosion and soiling of buildings, sculptures and painted surfaces. Corrosion of metals (when the atmosphere is humid) also take..

Materials to be transported include digested food, respiratory gases, hormones, excretory products, etc. The digested food includes sugars like glucose, amino acids, fatty acids and their derivatives. Blood which is the vascular tissue in man is over 90% water. Thus, ..

The materials to be transported across the plant body are water, minerals and food. Apart from these nutrients, substances like the hormones also have to be transport..

Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are solids. We say that solids have..

Matter and Materials - Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are soli..

Metallic surfaces exposed to acid rain are readily corroded. Textile fabrics, paper and leather products lose their material strength or disintegrate by the acid rain. Building materials such as limestone, marble, dolomite, mortar and slate are weakened on reaction with acid ra..

Limestone and clay are the chief raw materials used in the manufacture of Portland cement. Limestone provides calcium oxide. Clay gives silica, alumina and ferric oxide. Note: If lime is in excess, the cement cracks during setting and if it is less, the cement is weak in str..
