In an experiment scientists found out that surface ice does not completely transform into liquid water but ends up in a mixed state i.e. a mixture of ice water and crushed ice. Also, its thickness is about one hundredth the thickness of a strand of our hair. Finally, scientists concluded that ice becomes slippery because of the viscous nature of this film of water. Also, this film of water which is formed due to friction is the reason why an ice skater is able to surf on the top of snow. Reference: https://phys.org/news/2019-11-ice-sli...
