oxygen and hydrogen are a type of matter called gas
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.
The usual state of oxygen and hydrogen: they are gases at room temperature.
small amounts of hydrogen and oxygen are burned.

If it were a solid at room temperature, then that would be the state of matter. However, hydrogen is NOT solid at room temperature. It is a gas and that would be the state of matter.
