Answer: Temperature, Molecular Size of the particle, Polarity, Stirring
Explanation: Solubility of substances in water depends upon the below mentioned factors -
1. Temperature - Higher the temperature, higher will be the kinetic energy of the particles which will move in random directions. Thus the particle will nt remain as precipitate in the solution and will try to get dissolved.
2. Molecular Size of the particle - It is more difficult for the solvent to dissolve the particle with large molecular size as it will take high temperature to get dissolved.
3. Polarity - 'Like dissolves like' explains the polarity concept of the solubility. It means that the non polar solute will get dissolved in non polar solvents and polar solutes will get dissolved in polar solvents only.
4. Stirring - Stirring only helps to increase the speed of the process of solubility. It has nothing to do with the substance.
