An open capillary tube is lowered in vessel with mercury. The difference between the levels of the mecury in the vessel and in the capillary tube△h=4.6mm. What is the radius of curvature of the mercury meniscus in the capillary tube? Surface tension of mercury is0.46N/m, density of merc...
What is the formula for surface tension? Cohesion Force: The force of attraction between the molecules of the same substance is called the cohesion force. It is also called the intermolecular attraction. Adhesive force is the force of attraction between the molecules of different substances. ...
What is the shape of the catalyst particle? What is the size of the catalyst particle? A colloidal compound has 1017 spherical particles per gram with a density of 3.0 g cm-1 . What is the surface area per gram? What unit of measurement is used for measuring atomic radius? What ...
they often collide with each other or with the container holding the liquid. These collisions cause energy to be transferred between molecular entities. When enough energy is transferred to the liquid's surface, it can break the bonds of surface tension, causing the liquid to evaporate. ...

A liquid mirror telescope (LMT) may be made by rotating a reflectiveliquidmetal,such as mercury. The mirror surface assumes a paraboloid shape because the centripetal force depends on the square of the velocity. Because of this, the height of the spinning liquid metal is proportional to the squ...
