Metals tend to have a higher melting point than many other materials and they’re able to change forms when exposed to heat — unlike wood which simply decomposThe melting points of polar substances are higher than the melting points of nonpolar substances with similar siz For example the melting point of iodine monochloride which is polar is 27 degrees Celsius/806 degrees Fahrenheit while the melting point of bromine a nonpolar substance is 72 degrees Celsius/ degrees Fahrenheit

There are some metals like mercury that have such low melting points that they are better known as liquids Gallium is a metal that s known to melt in people s hand The alkali and alkaline earth metals in groups I A and II A are referred to as the light metals because they have low density low hardness and low melting points The high density of most metals is due to the tightly packed crystal lattice of the metallic structure

In this paper it is proposed to outline a method for the determination of melting points of those metals and alloys having high fusion temperaturThe application of the method as used to determine the melting points of alloys of tungsten and molybdenum will be givenMetals have high melting point because they have strong electrostatic force and to break this force we require high melting point while non metals have weak electrostatic force so it requires low melting point
