If water is being split into hydrogen and oxygen then a change of state (phase change) will occur if the water is in liquid form and the hydrogen and oxygen are evolved as gases. If water vapor is being split, then obviously no change of state occurs. Conversely, solid water in the form of ice could be split into hydrogen and oxygen gas, also undergoing a phase change.

What is usual state of oxygen and hydrogen?
The usual state of oxygen and hydrogen: they are gases at room temperature.
Is water being split to form two new substances hydrogen and oxygen a change of state?
No. It is a chemical change. Simply boiling water would be a change of state.
What state of matter is oxygen and hydrogen?
oxygen and hydrogen are a type of matter called gas
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water cannot be separated into hydrogen and oxygen by boiling. Boiling is a physical change which means the molecule doesn't change at all--liquid water and water vapor are both H2O. Water can be separated into hydrogen and oxygen using electricity, this would be a chemical change.
Is using electricity to separate water into hydrogen and oxygen a chemical change?
physical change
When water splits to to form hydrogen and oxygen is this a change of state?
No, it's a chemical reaction.
What is usual state of oxygen and hydrogen?

Oxygen and hydrogen are in what state?
Gas
How do you change oxygen and hydrogen to to liquids?
By cooling them
Is breaking water up into oxygen and a hydrogen gas a physical or chemical change?
Breaking water into the component parts of hydrogen and oxygen is a CHEMICAL change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
What is a sentence using hydrogen oxygen chemical change compound water?
There are many sentences that could include these terms. One such sentence is the following: The process by which hydrogen and oxygen convert to water is a chemical change. Also: water is formed in a chemical change involving hydrogen and oxygen.
