Q1: In general, the specific heats of aqueous solutions __________ with increase in the concentration of the solute.

ANS:B - decrease

The specific heat of a solution depends on various factors including the nature of the solute and solvent, as well as the concentration of the solution. In the case of aqueous solutions, the specific heat may change with an increase in the concentration of the solute. When a solute is added to a solvent to form a solution, the interactions between the solute particles and the solvent particles can alter the heat capacity of the solution. However, whether the specific heat increases or decreases with an increase in solute concentration can vary depending on the specific solute-solvent system and the concentration range. In many cases, the specific heat of aqueous solutions tends to decrease with an increase in the concentration of the solute. This is because the addition of solute particles disrupts the hydrogen bonding between water molecules, leading to a decrease in the ability of the solution to absorb heat. Therefore, the correct answer is: Decrease
