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 else can I help you with?
Is water being split to form two new substances hydrogen and oxygen a change of state?
No, the process of water being split into hydrogen and oxygen is a chemical change, not a change of state. During this process, new substances are formed through a chemical reaction, rather than a change in the physical state of the water molecules.
What state of matter is oxygen and hydrogen?
oxygen and hydrogen are a type of matter called gas
What is usual state of oxygen and hydrogen?
The usual state of oxygen and hydrogen: they are gases at room temperature.
Is using electricity to separate water into hydrogen and oxygen a chemical change?
Yes, using electricity to separate water into hydrogen and oxygen is a chemical change because it involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form separate hydrogen and oxygen molecules. This process is known as electrolysis.
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
When water splits to to form hydrogen and oxygen is this a change of state?
No, it's a chemical reaction.

What is needed to change the state or form of H20?
Electrolysis can be used to separate H2O into hydrogen and oxygen.
What state of matter is oxygen and hydrogen?
oxygen and hydrogen are a type of matter called gas
What is usual state of oxygen and hydrogen?
The usual state of oxygen and hydrogen: they are gases at room temperature.
What is the usual of oxygen and hydrogen?
The usual state of oxygen and hydrogen: they are gases at room temperature.
Does platinum change water back to hydrogen and oxygen?
Does platinum change water back to hydrogen and oxygen using a current
Oxygen and hydrogen are in what state?
Gas
How do you change oxygen and hydrogen to to liquids?
By cooling them
Is using electricity to separate water into hydrogen and oxygen a chemical change?
Yes, using electricity to separate water into hydrogen and oxygen is a chemical change because it involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form separate hydrogen and oxygen molecules. This process is known as electrolysis.
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.
