In a state of weightlessness, the shape of a candle flame will be spherical. Without the influence of gravity, convection currents do not form, causing the flame to become spherical as it is no longer pulled upwards. This phenomenon is ...

The liquid rises to a higher height than water in a capillary tube because the surface tension of the liquid is higher than that of water. This stronger surface tension pulls the liquid upward, resulting in a greater capillary rise ...
The movement of water from the roots of the plant towards its foliage is not solely due to capillarity. While capillarity contributes to water uptake by plants, other processes like transpiration and root pressure also play significant roles in the ...
The universal law of gravitation was propounded by Newton. Newton formulated this law in his work “Philosophiæ Naturalis Principia Mathematica” published in 1687. It describes the gravitational force between two objects and is a fundamental principle in classical mechanics and ...
The reason for water droplets not sticking to oily surfaces is primarily due to the lack of adhesive force. Water and oil have different polarities, resulting in weak adhesive forces between them, preventing water droplets from adhering to oily surfaces ...
