The water level remains the same when the ice cube melts. This is because a floating object displaces an amount of water equal to its own weight. Since water expands when it freezes, the volume of the melted ice cube ...
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 ...
