Using the following four words: surface area,
exposed,
collision(s),
rate of reaction,

explain why
crushing a solid into a powder increases the rate of reaction,

mistakes are ok

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
