Question

two tins A or B of same size, have one hole each of the same height. Tin A is filled with water, while tin B is filled with kerosene oil up to the same height. From which tin, would the liquid come out with greater pressure and why

Answer 1

From tin A, the liquid (water) floes faster than that of the liquid in tin B (oil).
This can be explained as : The interparticle forces between the particles of water are quite lose because of which water is less dense than oil , in which the interparticle forces are quite strong. The particles of oil have more difficulty to flow because the particles have to apply more force to leave their places as oil is denser than water.
As water is less dense than oil, it flows easily (even through a hole).
