Which form of colloid has gaseous particles dispersed in solid or liquid?

Which form of colloid has gaseous particles dispersed in solid or liquid? Correct Answer Foam

Foam is a type of colloid formed when gaseous particles remain dispersed in a liquid or solid medium. Example:- Whipping cream. Solid foams exist that have either closed cell or open cell. In closed cell foam gas forms discrete pockets, while in open cell foam gas pockets remain connected to each other.
