Answer 2

Answer:

An aerosol is defined as a suspension system of solid or liquid particles in a gas. An aerosol includes both the particles and the suspending gas, which is usually air. ... Primary aerosols contain particles introduced directly into the gas; secondary aerosols form through gas-to-particle.A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state. ... In this way, gels are a dispersion of molecules of a liquid within a solid medium.
