Given below are two statements : Statement I : Sublimation is used for the separation and purification of compounds with low melting point. Statement II : The boiling point of a liquid increases as the external pressure is reduced. In the light of the above statements, choose the correct answer from the options given below :

Step-by-step solution

Statement I: Sublimation is a process where a solid directly converts into vapor without passing through the liquid state. It is used to separate sublimable compounds from non-sublimable impurities. It is not specifically used for compounds based on having a low melting point, but rather based on their ability to sublime. Thus, Statement I is false. Statement II: The boiling point of a liquid is the temperature at which its vapor pressure equals the external pressure. If the external pressure is reduced, the vapor
