How does a suspension differ from solution?
A suspension is a heterogeneous mixture.
It is also where the particles may be visible to the naked eye, usually must be larger than 1 micrometre, and will eventually settle.
An example is whipped cream.
If left for a while it turns back into a cream and the gas bubbles are released. This is because the compounds are not chemically joined and they are just mixed, unlike a solution where something is dissolved.
For more help, I would suggest visiting BBC Bitesize or any other website that talks about the properties of both and from there you can take your time and cancel out their similarities and focus on their differences.
