For an atmospheric pressure of 101 kpa (abs) determine the heights of the fluid columns in
barometers containing one of the following liquids a) mercury, b) water, c) ethyl alcohol.

calculate the heights including the effect of vapour pressure and compare the results with those obtained
neglecting vapour pressure. do these results support the widespread use of a particular fluid for
barometers? explain the reason.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false
