Question

a glass jar contains a liquid of density d up to a height of h at a place where acceleration due to gravity is g and the atmospheric pressure is Pascal. what is the pressure at the free surface of the liquid?

Answer 1

Answer:

Density of air decreases at higher altitudes. (ii) Height of the air column above us also decreases. A variation between the altitude and pressure/density is shown in the graph given below. The graph above shows how both air pressure and air density decrease with increasing altitude.
