The formation of micelles takes place above a particular temperature called…………

Explanation

**Step-by-Step Solution:**

1. **Understanding Micelles**: Micelles are aggregates of surfactant molecules that form in a solution. They consist of a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail.

2. **Formation of Micelles**: Micelles typically form when surfactants are added to water. The surfactant molecules arrange themselves in such a way that the hydrophobic tails are shielded from water, while the hydrophilic heads interact with the water.

3. **Temperature Influence**: The formation of micelles is influenced by temperature. As the temperature increases, the kinetic energy of the molecules also increases, which can lead to the formation of micelles.
