As the humidity increases, the partial pressure of water vapor in the atmosphere (above the solution being evaporated) also increases. This results in more energy being necessary for the liquid water to evaporate, thus the higher the humidity, the longer it will take for evaporation of an aqueous solution to take place. This is essentially based on Dalton's Law of Partial Pressures.
Humidity is basically the amount of water vapour in the air. And evaporation is the vaporization of water into water vapour. So when the humidity is high there are already plenty of water molecules in the air so the water which gets vapourized into water vapour takes time to fill the gaps in the atmosphere and thus rate of evaporation is slow.

The rate of evaporation of an aqueous solution generally increases with temperature, not decreases. As temperature rises, the kinetic energy of the water molecules increases, allowing more molecules to overcome intermolecular forces and escape into the vapor phase. However, if the solution contains solutes, their presence can create a phenomenon known as "vapor pressure lowering," which may reduce the overall rate of evaporation compared to pure water at the same temperature. In summary, while temperature typically enhances evaporation, the presence of solutes can counteract this effect to some extent.
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
Because evaporation is accelerated after increasing of the temperature.

At limes of low humidity fluids evaporate more quickly because they can be easily taken up by the surrounding environment, at 100% humidity evaporation stops, evaporated water can be measured as relative humidity

The density of a solution typically increases on evaporation because as the solvent evaporates, the remaining solute becomes more concentrated in the solution, leading to a higher density.
You can increase the concentration of a solution by adding more solute (solid, liquid, or gas) to the solvent or by removing some of the solvent by evaporation. Stirring or heating the solution can also help dissolve more solute and increase the concentration.

When a solution of acid is diluted in water, the concentration of hydronium ions decreases. This is because the dilution increases the volume of the solution, causing the same amount of acid to be spread out over a larger volume. As a result, the concentration of hydronium ions in the solution decreases.
When carbon dioxide levels increase, the pH of a solution decreases. This is because carbon dioxide reacts with water to form carbonic acid, which lowers the pH of the solution.
This process is called precipitation. It occurs when the solubility of the solute decreases as the solution cools, causing the excess solute to come out of the solution in the form of solid particles.
The rate of evaporation decreases when common salt is added because the presence of salt increases the solution's boiling point and decreases its vapor pressure. This phenomenon, known as colligative properties, occurs because the salt ions disrupt the formation of vapor above the liquid, making it more difficult for water molecules to escape into the air. Additionally, the solution becomes more concentrated, further reducing the number of water molecules available to evaporate.
