Question

Q.Why does a gas mixed with another gas not form a colloidal system?

Answer 1

Using only the two major gases, we can consider the atmosphere to be oxygen dissolved into nitrogen. Another point: there are two colloid types called foam, where a gas is the dispersed phase. ... They form bubbles within the dispersing medium.

Answer 2

Answer:

A colloid system is an hetrogenous mixture of two distinct states of matter. It exhibit a dispersed phase which includes the particle which needs to be dissolved and a dispersion medium in which dissolves the dispersed phase. The dispersed phase remain undissolved in the dispersed medium in a colloidal system. The appearance of the colloid system is opaque or cloudy.

When the gases are mixed it forms a mixture of homogenous gas atoms, here the dispersed phase is gas and the dispersion medium is also gas, which can be called as solution rather than colloidal system as the mixture of gases forms translucent and transparent medium.
