law of flotation, for a body of density D and liquid L

D<L , body floats

D>L , body sinks

D=L, equilibrium.

yes, for D=L , the body is in equilibrium

pascal's law states that, for a liquid enclosed in a vessel , pressure at all the portions of the container is equal and when an external pressure is applied, it transmits equally in all directions.

as stated by pascal's law, for an external force applied , the pressure is distributed within , the distribution is only dependent on area of pistons instead of the vessel.

for a cylindrical vessel , the height should be equal to its diameter for making the force equal in wall and bottom.

Surface tension is the phenomenon caused due to intermolecular attraction between molecules of a fluid resulting the membranous behaviour of fluid. it is also defined as the energy required to increase the surface area of a fluid by a unit.

surface tension is the force for membranous behaviour, since force is independent of the area. surface tension is also independent of area. thus, for a fluid , value of surface tension for a fixed depth, temperature and standard conditions, value of surface...

Our sensation of taste is via tongue. the more the tongue tingles, the more we feel tasty. Cold soup has more surface tension because of low temperature resulting high attraction between the molecules. on the other hand, hot soup has low surface tension because of which, instead of getting attracted to other soup molecules,it sticks to our tongue and it tingles. thus, hot soup feels tastier than cold soup.
