How would you change liquid water into ice?

Answer 1

I would fill an ice cube tray and put it in the freezer (lower the temperature).

You change liquid water into ice by removing energy from the liquid water. You might do that by exposing it to something at a temperature below freezing. You could actually get some ice by spraying it through a nozzle into near vacuum. As the water sprayed through, a lot of energy from the liquid water would be used to vaporize some of the water - potentially dropping whatever liquid was left into ice.

A second way would be to put it under very high pressure. While at lower pressures, increasing pressure will cause ice to melt (which is one of the reasons ice skates work), when you get above about 200 MPa, increasing the pressure will solidify the liquid water. Of course when you get above the critical temperature you are really solidifying a supercritical fluid, not a liquid.

Answer 2

Put it in a hot and dry area and let it melt. Good Luck! :)

Ice Melts From a solid for when it becomes too warm for it to hold a solid form (It must maintain a cold temperature to stay solid) Just remove Ice from a cold place to a warm place!

no, no. it melts naturally.

Answer 3

When the liquid particles are exposed to cold temperatures they stop vibrating and stay still; And the particles become closer to each other thus turning into a solid (ice).
