Gas stoves sit in kitchens, ready to heat pots and pans whenever needed.
At the base of each burner, the pilot light maintains a small, steady flame that burns without pause.
This flame sustains itself through a continuous supply of gas at low pressure. The gas emerges from a tiny orifice, mixes with air, and combusts repeatedly in a small cycle.
The burning repeats endlessly, drawing just enough fuel to persist hour after hour, day after day.
The process runs independently, whether knobs are turned for cooking or the kitchen stands empty. No observation or input affects its operation.
The gas stove stands prepared by this constant pilot light burning, enabling immediate response to any call for heat.
