When an electric current passes through water during the process of electrolysis, two gases are formed. One gas has a boiling point of -183 C and the other has a boiling point of -253 C. Has a physical change or chemical change occurred? Explain.

I think it is a chemical change, but I'm not sure. It could also be a physical change because the water is just turning into a gas, which is a physical property of water. But, chemical change also makes sense because I think the water changed into different compounds. I'm really confused, can someone please help? Thanks. (=
