Why does gas cooking double the amount of moisture released into the air during cooking?

Gas cooking generates more moisture in the air primarily because of the combustion process itself. When natural gas or propane burns, it reacts with oxygen and produces not only carbon dioxide but also water vapor as a by-product. This water vapor is released into the air every time gas is used for cooking.

Understanding this principle is important for kitchen design and ventilation considerations. In contrast, options discussing steam generation or higher heat outputs do not directly account for the specific by-products of gas combustion. While gas cooking may create higher temperatures or steam, the unique factor contributing to increased moisture is indeed the water vapor released from combustion.

The cleaner burning aspect of gas compared to electric does not contribute to this phenomenon of increased moisture, as it primarily relates to the combustion process rather than the type of fuel source used. Recognizing the significance of water vapor as a combustion by-product clarifies why gas cooking can lead to increased humidity levels in the kitchen environment.
