A pot filled with cold water is placed on a stove burner. The heat source beneath it is activated, whether by igniting a gas flame or energizing an electric coil.
In the moments that follow, the water displays no alteration. Its surface remains perfectly smooth and clear. No bubbles rise from the depths. No steam gathers or drifts upward from the pot.
Time advances steadily over the next several minutes. The burner continues its operation. Repeated glances at the pot confirm the water's persistent stillness and transparency, unchanged from the start.
After this interval, visible motion appears. Bubbles form along the pot's bottom and stream upward. They breach the surface in quick succession, agitating the water into a lively roll. Steam rises noticeably into the surrounding air.
The boiling state is now clearly observable.
The sequence underscores the latency between applying stove heat and the water's boiling response. The initiating action takes place promptly, while the visible outcome emerges solely after a delay marked by the absence of any effect.
