What effect does temperature have on the solubility of a solid solute in a liquid solvent?
Radhika Krishna gave you a great answer but i want to add a point
ALWAYS remember to consider amount inmoles NEVER in grams for example is 18g water is mixed with 49g of h2so4 then convert it to moles annd then consider which is in greater amount.
here if we consider in gram then h2so4 is higher in amount but we dont have to consider it in gram calculate moles first.
we have 1 mole of water and 0.5 moles of sulphuric acid so water is solvent while sulphuric acid is solute.
it is because in this solution sulphur has less no of moles present in this solution then water.

(1) The ability of the solute to participate in hydrogen bonding interactions with the solvent, either as H-bond donors or acceptors. For example, hydrogen chloride and ammonia are both highly soluble in water.
(2) The temperature. Unlike solids, gases are MORE soluble in liquids at lower temperature. This is why cold soda loses its fizz when left to stand at room temperature.
(3). The pressure of the gas. You have probably notices how carbon dioxide is released from champagne and ofher carbonated beverages when the cork is removed. The beverages are bottle under pressure and removing the lid drops the pressure.

In case of endothermic solubility, solubility increases with increase in temperature while in case of exothermic solubility , solubility decreases with increase in temperature. As in most of the cases solubility is endothermic and hence there is incerase in solubility with increase in temperature.
It is very easier to check whether solubilty is endothermic or exothermic. If there is decrease in temeperature of solution with respect to solvent and then it is endothermic solubility while if there is increase in solution with respect to solvent it is exothermic solubility.
According to Le Chateliar’s Principle, equilibrium moves in the direction in which effect of disturbance is minimum. Hence in case of endothermic solubility there is increase in solubility with increase in temperature.

For the dissolution of solid in a liquid, the solubility increases with increase in temperature.
The substances that are solids at room temperature and pressure tend to become more soluble when the temperature rises. Heating a solution of a solid makes it easier for the particles of solid to move between the solution and the solid phase. The Second Law predicts that they will shift to the more disordered and more highly dispersed, and therefore, more probably solution state.
As the temperature of the liquid increases, the solubilities of gases in that liquid decreases. We can use the Second Law of Thermodynamics to explain why. Heating a solution of a gas enables the particles of gas to move more freely between the solution and the gas phase. The Second Law predicts that they will shift to the more disordered, more highly dispersed, and therefore, the gas state. This is the case in the absorption unit operation in chemical engineering.

Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute.

Usually the greater the Temperature the more soluble a solute will be. There are a few exceptions. And temperature can only increase so much (water boils a 100C) in the case of aqueous solutions

In general terms most compounds that dissolve in a liquid absorb heat that reflects the (endothermic) energy required to dismember the crystal lattice and the energy associated with solvation of each solute molecule. The amounts are thermodynamic quantities known as the heat of solution for the solvent-solute system.
On the basis of the le Chatelier principle - which predicts that any physical constraint imposed on a system in equilibrium will readjust to remove that constraint - any absorption of heat during the solubilisation process will respond to heat input by increasing both the rate of solubilisation and the concentration at saturation.
Occasionally anomalies occur due to the formation of different hydrates during the solubilisation process; eg, CaCl2 forms four different hydrates (1, 2, 4 and 6 water molecules per molecule of CaCl2) that affect the rate of dissolution as each hydrate is formed at various concentrations in the solubilisation process.
A further factor in determining the rate of solubilisation is the concentration gradient between the liquid solvent interface and the solute. To maximise the gradient and, therefore, the rate of solubilisation means stirring and maintaining agitation until saturation is achieved.

In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.

Although gas solubility usually decreases with increased temperature, it is plausible that gas solubility could increase for nonpolar gases in nonpolar solvents. Only weak London dispersion forces are present between nonpolar molecules, so the solvation enthalpy in such a solution would be considerably more positive than that of the same gas in water. If solvation is an endothermic process, adding heat will cause the equilibrium to shift towards the formation of the solution.
These are simply my thoughts based on general knowledge of solubility equilibria, so an answer that is supported by empirical data would be greatly appreciated!

Vinegar is typically a solution of 5–20% acetic acid (CH₃COOH) and water. A solution of ~99% acetic acid in water is called glacial acetic acid. You can dilute vinegar further by adding more water and mixing.
Terms like solute and solvent are not always the same for a given compound. Because of this, these terms are used when referring to specific solution. So vinegar is the solution, the solvent is water and the solute is acetic acid.

(1) The ability of the solute to participate in hydrogen bonding interactions with the solvent, either as H-bond donors or acceptors. For example, hydrogen chloride and ammonia are both highly soluble in water.
