Answer 1

'It increases the surface area, allowing more particles of solute to come in contact with the solvent.'

Answer 2

## Step 1The rate at which a solute dissolves in a solvent is influenced by several factors. One of these factors is the surface area of the solute. ## Step 2When a solute is crushed into smaller pieces, the surface area of the solute increases. This is because there are more particles exposed to the solvent.## Step 3With an increased surface area, more particles of the solute come into contact with the solvent. This increases the rate at which the solute dissolves in the solvent.## Step 4The other options provided, such as increasing the kinetic energy of the solvent, increasing magnetic attraction, or making particles of the solvent move more quickly, do not directly contribute to the rate of dissolution of the solute.
