Does ice melt or remain frozen at 0 degree celcius?
Thanks to latent heat (look up Clausius-Clapeyron equation for more details)
Are you adding or removing energy (heat)? Are you increasing or decreasing pressure?
no energy is removed or added and pressure is at a constant 1 atm.
I think the answer is that it remains frozen. The triple point is 0.01C.
Tehno is right, it does do both. Molecules are constantly joining and departing from the surface at the same time. The ratio stays about the same unless the temp is added or removed.
The triple point is not at 1 atm pressure though!
H20 does not have a triple point at atmospheric pressure.
lol...if that was the case we'd be dead.
In general there is a coexistence region whereby two phases will be simultaneously present. This happens over an extended temperature range and if predicted by the van der Waals equation of state. I am unsure what this is for water but there is no definate point at which we have either a totally water or totally ice, just proportions of either.
oops i didnt read that pressure will be constant , sorry... well ice will start melting atzero degree celsius
so does it remain frozen...or does it start to melt???
It takes energy to melt ice. If you don't add any, the ice won't melt.
