Open in App
Solution

When the surfaces are too smooth the irregularities between them are reduced. This perfectly smooth surface interface lacks any free voids through which air can enter, thus creating a perfect vacuum between the two surfaces. This vacuum leads the atmospheric pressure play its role and the surfaces are clinged to each other.
