Solution and suspension are

Answer 1

Suspensions and solutions can be liquids.

Suspensions are in liquids but also in gases; they are not homogeneous.

Solutions are genarally considered as liquids (the term "solid solutions" are sometimes accepted). They are homogeneous.

Answer 2

Solution is a homogeneous mixture of two or more substances, where one substance is dissolved in another. Suspension is a heterogeneous mixture where particles are dispersed in a liquid but are large enough to settle out over time.
