Why does the humidifier make a stove's flame orange?

The humidifier changes the color of the stove’s flame because it adds water vapor to the air around the fire.

Imagine you're lighting a candle in your room. The flame is usually yellow or orange, right? Now imagine you open the door to a steamy bathroom, all that hot water vapor mixes with the air. Suddenly, the candle’s flame looks more orange than before. That's what happens when the humidifier adds more water vapor, like opening that steamy bathroom door.

A stove’s flame is made of tiny particles called gas molecules. When there's not much water vapor in the air, those gas molecules burn in a way that makes the flame look blue or yellow. But when you add more water vapor, like from a humidifier, it changes how the gas burns, making the flame look orange, just like your candle did in the steamy bathroom.

It’s like giving the fire a little extra help to turn orange instead of staying blue. The water vapor is like a friend helping the flame change color!
