A horizontal tube of length `l =100 cm` closed form both ends is displaced lengthwise with a constant acceleration `omega`. The tube contains argon at a temperature `T = 300 K`. At what value of `omega` will the argon concentrations at the tube's ends differ by `eta = 1.0 %` ?

Text Solution

Verified by Experts

The constant acceleration is equivalent to a pseudo force wherein a concentration gradient is set up. Then
`e^(- M_Aw 1//RT) = 1 - eta`
or `w = -(RT 1n(1 - eta))/(M_A l) = (eta RT)/(M_A l) = 70 g`.

A column of mercury of 10cm length is contained in the middle of a narrow horizontal 1m long tube which is closed at both the ends. Both the halves of the tube contain air at a pressure of 76 cm of mercury. By what distance will the column of mercury be displaced if the tube is held vertically?

Shows a cylindrical tube of radius 5cm and length 20cm. It is closed by a tight-fitting cork. The friction coefficient between the cork and the tube is 0.20. The tube contains an ideal gas at a pressure of 1atm and a temperature of 300K. The tube is slowly heated and it is found that the cork pops out when the temperature reaches 600K. Let dN denote the magnitude of the normal contact force exerted by a small length dl of the cork along the perphery (see the figure). Assuming that the temperature pf the gas is uniform at any instant, calculate(dN)/(dl).
