Q1: Boiling point of a solution as compared to that of the corresponding solvent is

ANS:B - more

The boiling point of a solution, compared to that of the corresponding pure solvent, can vary depending on the properties of the solvent and the concentration of solute particles in the solution. This phenomenon is known as boiling point elevation. When a non-volatile solute, such as a salt or a sugar, is dissolved in a solvent, it disrupts the formation of solvent vapor molecules at the surface, which are necessary for the solvent to transition from liquid to gas phase during boiling. As a result, the solution requires more energy to reach its boiling point compared to the pure solvent. This leads to a higher boiling point for the solution. So, in general, the boiling point of a solution is higher than that of the corresponding pure solvent. Therefore, the correct answer is "more".
