yes .. changes in properties...

Umm... It can be more than one answer, it does split into to gases at room temp, and it does change into a different chemical make up. Since it no long has H and O together. But this isn't a reaction, since it doesn't have to new "compound" being made. Compound is a group of more than one element
But if you just want to know state, then yes. As long as the temp doesn't change then when water is liquid, H and O are gases.

Yes, but only at STP (Standard Temperature and Pressure).
Water, a liquid has become 2 gases. Both H and O are gases at STP.
However, you have to specify what conditions exist. The result is dependent on Pressure and Temperature conditions, according to the formula PV = nRT.
If water is frozen then split into H and O, both can be in liquid state, so therefore the answer is no, if you were referring to water at STP, a liquid state, therefore there is no change of state.
Therefore, your answer depends on initial conditions of Pressure and Temperature, and of course the final condition of Volume.
When I posted this, no one before me mentioned it.

That is definitely a change of state. You are changing a liguid into 2 gasses.

yes because water is a liquid state then it changes into two different gasses

I would say so. They're going from a liquid compound to a pair of gaseous elements.

the power generated = I^2 * R = 3*3*60 =540 WATTS. IN 6 MIN (=360 SECONDS) THE ENERGY GIVEN WILL BE 540*360 JOULES. WATER QUANTITY IS 5KG SO, THE ENERGY GAINED BY WATER=ENERGY LOST BY HEATER 360*540 = 5(MASS) * 4200 (SPECIFIC HEAT OF WATER) * T (DIFFERENCE IN TEMPERATURE) SOLVING \ T=9.25 DEGREES

yes its a change of state as the elements which form it are gaseous.

yes it is
water is a liquid
decomposing it using electrolysis forms O2 and H2 which are naturally occuring GASES

yea changes in properties

no. its not a change of state because its not a phisical change its a chemical change.
