Question
The weather report reads, "Temperature 20°C : Relative humidity 100%". What is the dew point?
Advertisements
Solution
Here,
Relative humidity = 100%
RH = `"Vapour pressure of air"/"SVP at the same temperature"` = 1
⇒ Vapour pressure of air = SVP at the same temperature
So , the air is saturated at `20^circ`C . So , dew point is `20^circ` C .

Figure shows a cylindrical tube of radius 5 cm and length 20 cm. 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 1 atm and a temperature of 300 K. The tube is slowly heated and it is found that the cork pops out when the temperature reaches 600 K. Let dN denote the magnitude of the normal contact force exerted by a small length dlof the cork along the periphery (see the figure). Assuming that the temperature of the gas is uniform at any instant, calculate `(dN)/(dt)`.
