Question

Gems and rubies, coloured glass are solid in solid type colloids.

Enter 1 if true else enter 0.

Answer 1

A colloid is a heterogeneous system in which one substance is dispersed (dispersed phase) as very fine particles in another substance called dispersion medium.

When both the dispersion medium and dispersed phase are solid, these are called solid in solid type colloid.

Examples of solid in solid colloid types are Ruby glass, pearls, some gem stones and alloys etc.

Hence, it is a true statement.
