what are the phases of water?

Question

what are the phases of water?

Answer 1

The simple answer is solid, liquid and gaseous, the same as all other materials. However, if one wants to probe a bit deeper:



1. One can imagine that if the water were subjected to extreme conditions, that it could form a plasma, the fourth state of matter.



2. There are many forms of the solid version of water, ice:



a. the simplest crystalline phase of ice is hexagonal, also known as Ih



b. under different conditions, other crystalline phases exist, known as II, III, V, VI, VII, VIII, IX and X.



c. ice can also exist in amorphous states, amorphous solid water (ASW), low density amorphous ice (LDA), high density amorphous ice (HDA), very high density amorphous ice (VHDA) and hyperquenched glassy water (HGW).



d. ice can also form a clathrate hydrate, in which gas molecules are trapped in an ice crystal lattice (deep on the ocean floor, on the outer planets in the solar system possibly, inside arctic gas pipelines).



And these are just the ones we have found so far. Depending on what you call a "phase", there are many, many phases of water.

Answer 2

Hi!

The water is the source of life.

In nature water can be found on three phases:



- gas: when it's temperature is more than 100 Celsius degrees (273.15 Kelvin)

Example: steam.



- liquid: when it's temperature is between 0 C and 100 C degrees (273.15 - 373.15 Kelvin)

Example: water that we drink



- solid: when it's temperature is more than 100 C degrees (373.15 Kelvin)

Example: ice



We can make water change it's phase by modifying it's temperature.



What is very interesting about whater is that it can exist

in all 3 phases in the same time. This is called THE TRIPLE POINT OF WATER (or something like that, i translated it from Romanian). At 273.16 Kelvin (not 273.15 Kelvin which is 0 Celsius degrees) water can be also gas, liquid and solid.

Interesting right?



"The triple point of water is the unique temperature at which the three phases of water (water vapour, liquid water and ice) coexist at equilibrium. The relation between degrees Celsius and degrees Kelvin is: t/°C = T/K-273.15. Thus, it follows from the definition of Kelvin that the temperature of the triple point of water is 273.16 K or 0.01 °C exactly."

Answer 3

This is true, there are three pahses of water, solid, liquid and gas. However, in the vacuum of space water does not exist as a liquid, only as a gas. Accordingly, in those deep freeze temperatures the gas is frozen. This is called GICE for gassious ice.

Answer 4

Gas, liquid, solid.



If you want to be more specific, you can say it's a solid at or below 32 degrees, a liquid between 33 and 211 degrees, and a gas, which actually it's a vapor, not a gas, at 212 or more degrees.

Answer 5

solid (below 0 degrees celsius.)



liquid (between 0.0001-99.9999 degrees celsius)



gas (anything that is 100-unlimited degrees celsius.)

Answer 6

gas liquid and solid
