Answer 2

Substances dissolve in the following way.

EXPLANATION:

• Dissolving is while the solute breaks up from a bigger crystal of molecules into a smaller groups or individual molecules.  
• This break up is as a result of getting in touch with the solvent.  
• In the case of salt water, the water molecules ruin off salt molecules from the larger crystal lattice.
• A solute is a substance whose particles are dissolved in a solution.
• The substance wherein the solute dissolves is called the solvent.
• Substances which dissolve without difficulty and effectively in water are known as water-loving or hydrophilic substances.  
• On the alternative hand, some solutes are non-polar and do not have any fine or poor prices.
• Things like salt, sugar and espresso dissolve in water.  
• They are soluble.  
• They generally dissolve faster and higher in hot water.  
• Pepper and sand are insoluble, they'll not dissolve even in hot water.
