what causes water to change state?

Answer 1

water in a liquid state has H2O molecules moving at a certain spead. when you apply temperature and/or pressure to those molecules they spead up and turn into a gas. if you remove temperature from them, the molecule slow down and become a solid.

Answer 2

Because AGW causes everything including male pattern baldness. They can't make their predictions stick, so they predict everything and even things they already know will occur and say its AGW. They are using the same line of logic as the fortune-tellers use, they don't really seem to care that this is not how the scientific method is done at all. The funniest part is if you actually look at the map they provided. Many of the "trouble" areas are in the part of Texas that tends to get a significant amount of precipitation if hurricanes hit the gulf. So if one of their predictions is an increase in hurricanes, then where are they? There are also portions of the map that are right along the coast line. So we have this clear, they are saying that the oceans will overtake this area and it will have a water shortage at the same time. What I really can not understand is how the peer review process for climate science has gotten so pathetic as to not catch any of this. I saw this within the first 30 seconds of looking at their map, yet peer review did not see the problems is their own logic? Its as if they don't even care anymore. They allowed the scaremongering piece about a 13 degree rise (when even the IPCC places the warming at 3 degrees) and the earth being uninhabitable by man. Seriously WTF? Someone just presented a piece saying that CO2 will cause poison ivy to flourish, seemingly ignoring all others plants that benefit. Are they going out of their way to demonstrate that their peer-review process is broken? Are they trying to demonstrate that their own bias has gotten in the way of true science? The warmers do not even notice this, but they don't notice their own hypocrisy. A poster extolled how well the IPCC model had done at predicting the current temps. He noted that 2010 was right on the money, but ignored that 2008 and 2009 were low, and that the only reason 2010 was correct was because of the large El Nino effect. Either way, the IPCC model is admittedly running a little high, but within the confidence intervals (this was a warmer saying this). The problem is that the IPCC is running a bit high, and this is the one the predicts 3 degrees of warming. The warmers on this site have constantly been trying to scare people with a model that predicts 7 degrees of warming. So they praise the ability of a 3 degree model to model the current temps, when it is indeed running high, but they turn around and say that the model is underestimating the heat rise and that a 7 degree models would be more appropriate. The saddest thing is that, they do not even care. They do not see this as scare mongering they do not see the contradiction. They just don't care. Pegminer, No I do not believe that we will have more hurricanes, just that a report outlining the effect of "climate changes" should at least have some internal consistency. So now you are only claiming that the "consensus" opinion of the consequences can be used. So you have scientists say that more hurricanes will arise, and when they don't, well thats alright it was not a "consensus" of scientists that beleived that. So tell me how this "consensus" works. How do we know what predictions have been vetted as being "consensus" in the scientific community? I personally love the strategy that you are employing. The whole well we weren't sure about that one occurring. Did you "scientists" have a meeting with palm readers to find out how to make anything look plausible?

Answer 3

Temperature

Answer 4

Temp. because if the change in temp. is cold then it changes to ice where the particles in the water are moving slower and become a solid. So when the temp. is hot it will be warm or beggin to boil because the particles are being stimulated and are able to move faster. or even become into a gas when the boiling water emits the water as gas.

Answer 5

Temperature.

Answer 6

Temperature (energy), of course. But also pressure.

Answer 7

rivers can change state, sometimes even change to another country.

Answer 8

temperature

Answer 9

anything from temperature, to agitation.

Answer 10

temperature.
