@JoshJamesification i mean why does the cold slow them down i know it reduces there kenetic energy but why???????

[icelcn]

@FreeKicksPFC Temperature is simply average kinetic energy. When something is "hot" it means the atoms that make it up are moving (and vibrating) really quickly.

Is that H2O molecule arrangement called the open structure of Ice?

[icelcn]

@thegreatMSG the "open structure" refers to the gap (vacuum) in the middle of the ice hexagonal rings, which you can see early on in this video. This is why ice has a lower density than liquid water.

@Loris42100 Trop cool c'te vidéo non ?

[Tamagot42]

What is the name of the song ? ;)

UNBELIVEABLE !!!!!!!

@FreeKicksPFC Cuz dey iz gettn colda

[FreeKicksPFC]

why do they slow down???? is it because if they are moving they are liquid?
