1.	7.32 What are colloids? Why is there no colloid inwhich both the disperse phase and dispersionmedium are gases?
Answer» In chemistry, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture the dispersed phase (call it gas #1) is already at the molecular level and disperses evenly throughout the dispersing medium (call it gas #2). It is completely homogeneous at the molecular level. It is a solution. An example of this is the atmosphere. Using only the two major gases, we can consider the atmosphere to be oxygen dissolved into nitrogen.

In chemistry, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture

the dispersed phase (call it gas #1) is already at the molecular level and disperses evenly throughout the dispersing medium (call it gas #2). It is completely homogeneous at the molecular level. It is a solution.

An example of this is the atmosphere. Using only the two major gases, we can consider the atmosphere to be oxygen dissolved into nitrogen.
