Why does micelle formation take place only at a particular temperature and not at low temperature?

Dear Student,

Please find below the solution to the asked query:

For the formation of a micelle, a particular concentration called Critical Micelle Concentration is required.
Above this concentration only  the surfactants form micelles and micelle formation takes place.
To reach this concentration, a temperature is required which is called Critical Micelle temperature or Kraft temperature.
Below the Kraft temperature, the surfactants don't form micelle. This is because at that temperature surfactants exist in the crystalline form, & are incapable of Micelle formation, but  when the temperature increases,  the entropy increases which causes the crystalline structure to break down and form micelles.
