In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids.

A fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases and plasmas. Fluids display properties such as flow, pressure, and tension, which can be described with a fluid model. For example, liquids form a surface which exerts a force on other objects in contact with it, and is the basis for the forces of capillarity and cohesion. Fluids are a continuum (or "continuous" in some sense) which means that they cannot be strictly separated into separate pieces. However, there are theoretical limits to the divisibility of fluids. Fluids are in contrast to solids, which are able to sustain a shear stress with no tendency to continue deforming.

you know that the change in pressure with heights is given as delta p equaling the density times jean times H or rather recon, say dealt age the change in height And so we can say that the change in heights with respect to the atmospheric pressure would be equal in the density times the acceleration due to gravity times the change in height divided by the atmospheric pressure. And so we can say Delta P over the atmospheric pressure would be equaling the density of air. 1.29 kilograms per cubic meter multiplied by 9.80 meters per second squared multiplied by the change in height of 380 meters. This would be divided by the atmospheric pressure of 1.13 times 10 to the fifth past scowls. And so the change in pressure is equaling 0.0 for seven atmospheres. This would be our final answer. That is the end of the solution. Thank you for
