Expert Answer:

Thermally or in presence of light we can not separate hydrogen and oxygen from water. 
If we supply heat or light then water molecule changes only its state that is from liquid to vapour state.
This is happening because of the strong intermolecular force of attraction present between water molecule which is known as a hydrogen bonding.
The partial negative oxygen atom of a water molecule is bonded with partially positively charged hydrogen atom of another water molecule with a hydrogen bond.
It is not easy to break this bond.
But in the presence of electric current, we can easily separate oxygen and hydrogen from water, this process of obtaining hydrogen and oxygen from water with the help of electric current is known as electrolysis of water.
