This depends if the particular cell membrane is permeable to the substance or not. If so, then if there was a larger amount of the substance on the outside, it would diffuse into the cell down the concentration gradient. For it to go the other way would require ATP used in active transport.

When there are different amounts of a substance on either side of the cell membrane the gradient result is called the concentration gradient. The permeability of the cell membrane will determine which substances can easily pass through the cell causing a change to the concentration gradient.

It is known as a concentration gradient which in diffusion will always flow from areas of high concentration to areas of lower concentrations.

osmosis
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
