• when we dissolve sugar in water it makes a solution.

Dissolution of different substances:

• Different solutes have different dissolution rates because of the different sizes of solute particles.
• Particles of soluble solute, with greater surface area, and high kinetic energy dissolve rapidly. Examples of soluble substances:- Salt and Sugar.
• Particles of insoluble substances dissolve are very little or negligible. Examples of insoluble substances: are oil and sand.

Conclusion:

So, In water certain substances dissolve rapidly, whereas certain substances very slowly.

Therefore, the given statement is true.
