Q1: The increase in the temperature of the aqueous solution will result in decrease of its

ANS:C - molarity.

The increase in the temperature of an aqueous solution typically results in a decrease in its density. This decrease in density leads to an increase in the volume of the solution for a fixed mass of solute and solvent. Since the mass of the solute remains constant while the volume of the solution increases, the weight percent of the solute decreases. So, the correct answer is: Weight % of the solute.
