A substance that gives off heat when dissolving in water will
have greater solubility at low temperatures. According to Le Chatelier's
Principle - if heat is a product of the reaction, increasing the
temperature will drive the reaction backwards.
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.)
Solubility and density are both temperature dependent. As temperature increases, kinetic energy increases and thus things become more soluble in solvents. Density decreases with increased temperature due to greater expansion.
Mostly, but not always, solubility increases with temperature. However in general it is impossible to say 'How', because this is very different for each solvent - solute combination and many other circumstances.
The OH group makes it slightly water soluble while the carbon group resists solubility. The 3-pentanol molecule is slightly water soluble.
Perhaps you mean the solubility of substances in water. Most solids have increasing solubility in water with increase in temperature, but certainly not all of them. Some solids e.g. Cerium Sulphate have decreased solubility in water at higher temperatures, while some solids show increasing solubility up to a certain temperature, above which the solubility decreases, such as Sodium Sulphate. The solubility of common salt, Sodium Chloride, is almost unaffected by temperature. Gases generally have lower solubility in water at higher temperatures.
Yes, heat can change the solubility of a substance. In general, an increase in temperature usually increases the solubility of solid solutes in liquids, while the solubility of gases in liquids decreases with increasing temperature.
we know that the salt nacl is formed from two competly disaccosiating acid , base ie hcl and naoh while in case of na2so4 naoh plus h2so4 weaker comparitively to hcl shows daviation
Yes, the solubility of gases generally decreases with an increase in temperature. This is due to the fact that as temperature rises, the kinetic energy of gas molecules also increases, making it easier for them to escape from the liquid.

the solubility of a solid increases with temperature while those of gasesdecrease with rise in temperature.
The OH group makes it slightly water soluble while the carbon group resists solubility. The 3-pentanol molecule is slightly water soluble.
because the carbonated of group 1A is stable while the carbonates of group 2A is not stable .....
Impurity
increases, decreases
As height increases, the velocity generally decreases due to the effect of gravity. This is because potential energy increases while kinetic energy decreases, resulting in a slower velocity.
