The melting and boiling points of covalent compounds are generally low. This is because of the fact that the forces between the molecules are weak and thus are easily overcome at low temperature..

One can overcome all the problems of poor oral health and have sparkling teeth. One is not ashamed but proud to smile. 3. Why is Cerec called a space-age ticke..

Measurement of Electrode Potential - The absolute value of single electrode potential cannot be determined because the oxidation half reaction cannot take place without the reduction half. To overcome this difficulty the standard hydrogen electrode (SHE) is taken as the standard or refere..

Escape Velocity - All bodies when projected vertically upwards fall back to earth due to the earth's gravitational pull. The maximum height attained by a body depends upon the initial velocity of the body. This does not mean that no object can escape earth's gravitational pull. We know that the spa..

, such as cyclosporin A, is used to inhibit the immunological mechanisms responsible for graft rejection. This drug is derived from a fungus, and it has largely overcome this problem. It inhibits T cells which are responsible for tissue rejection. But withdrawal of the drug may result in..

Every chemical substance is known by a specific name. But many a times these names are cumbersome, confusing, and do not provide information about its chemical composition. To overcome this, each chemical compound is represented by a chemical formula that gives its composition (constituen..

The vapour pressure of a liquid increases with increasing temperature. As the temperature increases, the number of molecules, which have larger kinetic energy to overcome the intermolecular cohesive forces, increases. As a result more molecules escape from the surface of the liquid and c..

It is used in spectacles for correcting myopia. along with convex lens it is used to overcome defects like chromatic aberration and spherical aberration (the failure of rays to converge at one focus because of a defect in a lens or mirror..

Crop plants are sensitive to light and temperature. The required exposure to sunlight and the right temperature determines the healthy growth of plants and ensures a good yield. Developing varieties insensitive to these factors will help in overcoming these constraints. Then these crops ..

When you sit in a chair, many forces act on your body. The pressure of the atmosphere pushes down on you and gravity pulls you towards the earth. You sit comfortable, because the muscles in your body push with equal force against the atmosphere above you. Your chair pushes up against the force of ..
