In a room with a single window, Zephyra is standing with her back to the window, and the wind outside is blowing inwards from the direction facing her. There's a candle on a table behind Zephyra, between her and the window. What happens to the flame of the candle when the wind blows in, and why does this happen? Respond very briefly.
The flame of the candle will flicker and may lean away from the window toward Zephyra, or it could be extinguished if the wind is strong enough. The incoming wind increases the airflow in the room, which disturbs the stable area around the candle's flame. This disturbance causes the flame to move in the air flow's direction, which is towards Zephyra since the wind is coming from behind her, blowing towards her back. The flame flickers because the wind creates turbulence in the air, which disrupts the smooth flow of gases from the combustion of the candle's wick. If the breeze is sufficiently strong, it could introduce enough cold air to lower the local temperature below the combustion point or blow away the heated gases that sustain the flame, causing the candle to go out.
