Natural gas is mostly methane. Methane’s chemical formula is CH4, with the C representing a carbon atom and the H4 representing four hydrogen atoms. When methane burns, it reacts with oxygen gas in the air. The carbon combines with oxygen to become CO2, aka carbon dioxide, and the hydrogen combines with oxygen to become H2O—aka water.

Since the reaction releases a lot of heat, the water starts out as steam, which is an invisible gas. When it hits the still-cool glass of the oven door, the steam cools and condenses into liquid.
