If so at what temperature does this occur?

Hi Nick
YES.
Water will dissociate into its constituent elements at high temperatures.
It's a complicated subject - for example, in the extreme temperatures used in Plasma Emission Spectroscopy, water is 'broken down' into its constituent elements, ions.
The temperature at which water will start to break down into its elemental components is 2,726.85 Centigrade.
The process is complicated, inefficient and does not run to completion. You are, in essence, attempting to introduce an instability within the water molecules to cause this dissociation.
You're looking at a temperature and pressure dependent equilibrium state, delG(T,P) = -RTlnK, and there is no one (T,P) state at which water abruptly ceases to be stable.
But - to keep it simple - if it's hot enough water will separate in to hydrogen and oxygen.
You may want to explore this more by refering to degree level physical chemistry literature or look at the theory behind cold fussion/water fuel cells - which are still regarded as unproven - BUT some of the fundamental laws used to try and explain them gives a usefull forum of study.

I do have faith in Creationism, yet no longer in the in many cases happening way. i've got faith that God made guy for the duration of the innovations-set of evolution. God gave us eyes to work out the data, and minds to evaluate what we see. in the beginning up, awesome after the form popular via fact the great bang, in spite of the fact that if in Einsteinian fashions or M-brane fashions, the actual universe consisted of extraordinarily plenty one sort of depend, sub-atomic debris of the two depend and antimatter. the two a type of annihilated maximum each and every thing, leaving hydrogen in great abundance. The hydrogen coalesced till the 1st stars have been born. whilst the main sequence, this is Hydrogen fusing into Helium, runs out, then the helium starts to fuse into heavier and heavier factors, culminating with iron. 2 milliseconds after a celebrity is converted into iron, it is going Nova, spreading it fairly is heavy factors throughout area. The very iron on your crimson blood cells became born in the heart of a great call. All factors have been formed in this form, which paved the way for a universe which could help life. So, specific, water is formed from 2 Hydrogen atoms and one Oxygen atom, and with out them, life does not be achieveable as all of us are conscious of it. God is the surprising Chemist, the surprising biologist. i admire technology, yet I ought to concede that God blew the spark of life into the 1st single-celled creature, which billions of years later led to life as all of us are conscious of it. desire this facilitates!

no, there is strong hyrdogen bonding between the molecules which prevents this from happening. however through the use of electroysis it is possible to seperate the hydrogen and oxygen atoms.

No. Even superheated steam does not dissociate (split up) into hydrogen and oxygen due to the very strong chemical affinity. Electrolysis is one method to separate and passing steam over hot copper etc. is another.

No!
No matter how much you heat it,it will not split in to its respective elements,instead the kinetic energy will increase with increase in Temperature!!
water will split only if you provide Electrons to Hydrogen to gain stability,and Oxygen to complete its Octet to gain a stable state!!

No, it is just gaseous water. Water bonds are very strong and water is a polar molecule, but I wont go into it as thats in Alevel and it looks like your not there yet.
