because increase in molecular werght increases the hydrophobic part and decreasesv the hydrophilic part which is soluble. therefore increase in insuluble part decreases the solubility.
It doesn't. As the temperature of water increases so does solubility.
The solute solvent interaction is not exothermic enough to overcome the hydrogen bonding between water molecules, which is stronger than van der Waals forces between solute molecules.
due to hydrogen bonding of alcohols with water.
With a rise of temperature, the solubility increases
Although the solubility of most substances increases with temperature (eg you can dissolve more sugar in water when it is hot than you can in the same amount of water when it is cold) with gases the solubility decreases with temperature, so that cold water will hold more gas than the same amount of hot water. As oxygen is a gas its solubility decreases as the water temperature increases.
solubility generally increases with a temperature increase
Oxygen solubility in water is strange and does not follow "normal" solubility rules along with many other gases. The solubility increases as temperature decreases.

As temperature (of the solvent) decreases and pressure (of the gaseous solute) increases the solubility of gases in water will increase.
The water molecules spread out as temperature increases, which allows the alum to dissolve more readily. Conversely, as temperature decreases, the water molecules become more compact which causes the alum to be less soluble.
Solubility of gases in liquids decreases with increase in temperature. When gases are dissolved in liquids, heat is evolved. Following Le Chatelier's principle, as the temperature increases, the solubility decreases. This is the reason that aquatic species are more comfortable in cold water as compared in warm water.
The amount of dissolved oxygen decreases when water temperature increases. Warm water is unable to dissolve as much oxygen gas.
Temperature has a direct effect on the concentration of dissolved oxygen in water. As the temperature of the water increases, the solubility of oxygen decreases and the concentration of dissolved oxygen will decrease. Conversely, as the temperature of the water decreases, the solubility of oxygen increases and the concentration of dissolved oxygen will increase. Additionally, warmer water is generally less dense than colder water, resulting in less efficient oxygen transfer.
As the temperature increases:The solubility of a solid in a liquid increasesThe solubility of a liquid in a liquid increasesThe solubility of a gas in a liquid decreases(The solubility of liquids and solids increase as temperature increases, while the solubility of gases decreases as temperature increases.)
Temperature changes affect the solubility of CO2. Carbon dioxide is more soluble in ocean water due to the ocean temperature being low.
