leave it in room air for a few hours
you freeze it XD
Water is water, whether solid (ice), liquid or gas.
After melting, ice will turn into water. This transition is reversible, meaning the water can freeze back into ice if the temperature drops below its freezing point.
It could be instantly. In the far north of the world you can throw a cup of boiling water in the air and it will turn into ice before it hits the ground
No, salt water is not able to turn to ice.
Water don't turn instantly into ice; this depends on the temperature.
Since the water is at a higher temperature than the ice, it transfers heat to the ice. This in turn raises the ice's temperature above its melting point of 32oF which turns the ice to water.
the ice can melt and turn to water, or sublimation can occur and the ice turn to water vapor.
Turning water into ice in seconds can be done in a few ways. You can flash freeze the water for example.
For example, to melt ice, you need to add heat energy. To freeze liquid water (to turn it back into ice), you have to remove heat energy.
Ice is frozen water, when you take it out of an environment that is freezing(below 32F) and into an environment that is warmer than freezing(above 32F) it will melt or turn back into water as water is thawed ice.
ice is water. its just that the molecules of water slow down the vibrations that are moving and they turn into a solid, and what you get is Ice
