Question

have you ever skated on ice or seen someone do so? how can people glide smoothly on ice?​

Answer 1

Explanation:

The ice molecules loosen up creating a friction less surface. This water then acts as a lubricant, resulting in smooth motion over the ice. The water molecules on the ice surface are in between a liquid and solid state, allowing such smooth motion. Thus, the ice skater are able to glide smoothly across the ice.
