What is the freezing point of water, melting point of ice, boiling point of water?

Under standard conditions, that's where water freezes and melts (Oo) and where it condenses and boils (100oC)

Yes, that is right at Standard pressure (101.3 kPa) Water freezes at 32 F(0 C) and boils at 212 F (100 C)

If Ice would be melting to water, then yes that is correct. 0 degrees C is when water turns into Ice. So if it is already Ice and it is at 0 or above, it will start melting. So 0 C is both the freezing point of water and the melting point of Ice. Hope this helps.

To convert those number to Farenheit, it is for freezing 32 degree and boiling is 212 degrees. Whether you are freezing or melting the temperature is the same.

freezing Point of water is 0 deg Celcius Melting point of ice is 4 deg celcius Boiling Point of water is 100 deg celcius.

Have you ever watched water turn into ice? its interesting, or a least it is to me. when energy (heat in most cases) is added to a system such as ice then it will increase in temperature. The rate of how fast the temperature changes is based on the material's specific heat ( "c" if you look this up elsewhere). Once the system reaches the phase change point it must meet a certain requirement to pass into the next phase. For ice into water the requirement is 333 j/g (joules per gram of substance). This value is called heat of fusion (weird name especially for that fact that fusion is also a name for a process in nuclear chemistry) if you want water to become ice then the name is crystallization (its the exact same value of fusion just with a negative in front of it) so if something is at the point where phase changes occur, it doesnt necessarily mean that it will change phases. The phase change only occurs if the gain or loss of joules is met for that specific substance. .......and because i can: for water (H_2_O) l to g vaporization 2260 j/g s to l fusion 333 j/g s to g sublimination 2593 j/g (fusion and vaporization added) l to s crystallization -333 j/g g to s deposition -2593 j/g (not demonstrated by water; metals can demonstrate this) g to l condensation -2260 j/g certain things have weird phase changes, like dry ice: the vaporization is at the same point for fusion, so the liquid part gets canceled. P.S. all measurements are accurate at 1 atm (atmosphere/sea level), there are ways to compensate for this when at different barometric pressures.
