Question

when does water actually under go change of state​

Answer 1

Explanation:

water changes its state at two temperature-

1.at 100 degrees,it changes to gaseous state.

2.at 0 degree it changes to ice.

hope this helps you...

Answer 2

Any substance can occur in any phase. Under standard atmospheric conditions, water exists as a liquid. But if we lower the temperature below 0 degrees Celsius, or 32 degrees Fahrenheit, water changes its phase into a solid called ice. Similarly, if we heat a volume of water above 100 degrees Celsius, or 212 degrees Fahrenheit, water changes its phase into a gas called water vapor. Changes in the phase of matter are physical changes, not chemical changes. A molecule of water vapor has the same chemical composition, H2O, as a molecule of liquid water or a molecule of ice.
