Why there is huge difference in M.P. and B.P. Of Oxygen (M.P. - 54K,B.P.- 90K) and sulphur (M.P. - 393 K, B.P. - 718 K)
S6, S8, Sn>>8 vs. O2? Google "polymorphism."Dragosagaragarwal said:Why there is huge difference in M.P. and B.P. Of Oxygen (M.P. - 54K,B.P.- 90K) and sulphur (M.P. - 393 K, B.P. - 718 K)
The melting point of a substance is the temperature at which it changes from a solid to a liquid state, while the boiling point is the temperature at which it changes from a liquid to a gas state. In other words, the melting point is where a substance begins to melt, and the boiling point is where it begins to boil.
Melting point and boiling point can be determined through various experimental methods, such as heating the substance and measuring the temperature at which it changes state, or using specialized equipment like a melting point apparatus or a boiling point apparatus. The purity of the substance can also affect its melting and boiling points.
Melting point and boiling point are important physical properties of substances that can provide valuable information about their chemical composition and purity. They can also be used to identify and characterize substances, as different substances have unique melting and boiling points.
The melting point and boiling point of a substance are intrinsic properties and do not change, unless the conditions (such as pressure or purity) also change. However, substances with impurities or mixed compounds may have a range of melting and boiling points rather than a specific value.
The strength of intermolecular forces, such as hydrogen bonding or London dispersion forces, can affect the melting and boiling points of a substance. Generally, the stronger the intermolecular forces, the higher the melting and boiling points will be, as more energy is required to break these forces and change the state of the substance.
