Why does finely grinded substances dissolve faster than a substance that isn't grinded...(the answer should have to do something with the surface to volume ratio)

grinding the substance increases the surface area to volume ratio which increases the rate of diffusion or in this case , the rate that the substance dissolves

This is less surface volume to dissolve: the molecules are smaller which means they are usually easier to break up.
