Document Summary

Does pressure depend on orientation of block? as b) smallest surface area, (cid:15482) greatest pressure. while force is the same. Liquid : takes shape of container (cid:8869) Gas : density is lowest, expand to fill. Both flow , but liquids cannot be compressed as easily volume. Pressure in a fluid caused by : weight offluid & collisions with walls of container significant in gases : kinetic energy significant in liquids gas is less dense, doesn"t experience effect of gravity as much . Q 12. 6 weight of a liquid column: total weight = mg =pvg =p cd a)g . = wz = pd a_ =p dog . an. Mmmm a don"t forget atmospheric pressure total pressure=pwtpair. Key formula /p=pdg- how it changes wth depth . kntfwn pressure. This is : pascal "s principle: basically , at the same depth, pressure is the same in a connected fluid .
