Answer 2

Answer:

Yes. Icing is an example of foam.

Explanation:

Foam is a type of Colloid. A Colloid contains substance with sizes too small to be seen by naked eye suspended throughout another substance.

The different types of Colloids are: -

Sol.           Solid particles in liquid

                  medium.

Emulsion.  Liquid particles in liquid

                   medium

Aerosol.     Liquid/ solid particles in

                   gaseous medium

Foam.        Gaseous particles in

                    liquid or gas medium.

Icing used on cake and pastries is made by whipping either egg white or cream in such a way that air gets trapped in the liquid( egg white or cream).

Thus ,it is an example of colloid( foam).
