Did you know that when you do ice skating you’re actually skating on a temporary thin film of liquid water!?
Maybe we could clear you about how it happens!
We all know that the ice is water in solid form.
Some of you already know that, at normal atmospheric pressure (1 atm) of Earth’s surface, the ice undergoes fusion (melting) at a temperature of 0°C. That’s physics knowledge!
Besides that, everyone knows that the ice skates do not have wheels, but rather slim and smooth blades.
What happens is that the ice skater’s weight on the blade of the ice skates leads to increased pressure on the surface of the ice. This bigger pressure combined with the blade friction on the superficial ice sheet caused by the ice skater movement results in momentary melting ice in the lane where the ice skates pass.
So when you’re ice skating you are actually sliding on a thin film of liquid water surface and not on true ice (water in solid form).
But how is it possible that the liquid water film doesn’t accumulate in the ice rink with so many ice skaters skating in it?
It’s simple, just after the passage of the blade the pressure returns to normal and since the temperature in the ring remains below 0 ° C, the water returns to freeze!
