Foams are relatively unstable with lifetimes that increment with increasing viscosity of the liquid phase.

Foams are relatively unstable with lifetimes that increment with increasing viscosity of the liquid phase. Correct Answer True

Foams are large air bubbles differentiated by thin films of liquid with thicknesses in the range of those of colloids. The term also is applicable to material in a lightweight cellular spongy or rigid form.
