Ice melts under ice-skating blades for two reasons: friction and the weird physical properties of water.
Notsurprisingly there is some friction when the blade slides across the ice, and the friction converts to heat - which can help melt the ice.
The strange thing about water is that it actually expands upon freezing. Applying pressure to it - consequently making it more dense - actually shifts the ice back towards the physical state of liquid, which is more dense. This phenomena is not true over the entire pressure-temperature phase space of solid water, but it is true in the phase space near atmospheric pressure and normal ambient temperature conditions.

What happens to the molecules in an ice cube when the ice melts?
They are able to move freely.
Which process could cause ice to form a thin layer over a lake?
Freezing is the process that would cause ice to form a thin layer over a lake. Ice is formed when a liquid is cooled.
What is a drink poured over crushed ice?
a slushie???
Lightweight vessel for travelling fast over ice and water?
I got it to be a scooter because it fits :)
How does a heated ice scraper score over a regular ice scraper?
A heated ice scraper is significantly better because it can melt thick ice and the heat that it produces makes it easier to remove ice from windows. You can purchase a heated ice scraper online from retailers such as Amazon.
What allows ice-skaters to glide smoothly over the ice?
The zamboni which is a contraption that makes the ice smooth
Two ice skaters glide into each other at full speed. What will happen?
They would fly each a different direction.
How skaters skate on ice using phase diagram of water?
As we glide across the ice, we exert pressure on the thin blade, and are therefore creating a small stream of water in our path by melting that ice. The water between the blade and the ice is what we really glide across. Right when we stop exerting pressure, that water freezes almost instantly due to the cold temperature surrounding it
What has the author Dorothy Hamill written?
Dorothy Hamill has written: 'Dorothy Hamill on and off the ice' -- subject(s): Biography, Figure skaters, Ice skaters, Juvenile literature, Women figure skaters, Skaters
What are several meanings of Edmunds statement that the frost was over What difficulty did the thaw cause the white witch?
The White Witch was know longer able to use her sled for transportation. There was no snow or ice left for it to glide over.
Do ice skaters get trophies?
No... they get gold metals
Where do figure skaters train?
Figure Skaters train at an ice rink to practise their technique based on which level they are on.
What is the definitiion of ice skating?
To be able to wear shoes with metal blades attached to the sole of them. To then allow the human body to wear these "skates" to glide across ice.
Why were the roller skates invented?
to get from place to place when there wasn't ice... they complimented ice skaters
Why is Michelle?
she is famous because her ice skating was the most beautiful of all the other ice skaters.
When figure skaters fall do they have to keep skating or can they leave the ice?
they have to keep skating. Then after they can put ice on
How does ice temperature affect ice skating?
because ice is cold so it whares off and the ice skaters sometimes get cold
