In a state of weightlessness, the shape of a candle flame will be

In a state of weightlessness, the shape of a candle flame will become spherical, denoted by option [C]. Without the force of gravity, there’s no upward direction, so convection currents don’t form. Consequently, the flame doesn’t elongate upwards, instead, it expands in all directions equally, forming a spherical shape. This phenomenon is observed in microgravity environments like space, where objects experience weightlessness and gravitational effects are minimized. Therefore, in such conditions, the candle flame deviates from its typical teardrop shape seen on Earth and adopts a spherical form. This change in shape is due to the absence of gravitational force pulling the flame upward, leading to a more symmetric distribution of heat and gases around the flame’s core.
