The compressibility of a gas is less than unity at STP, therefore,
Two closed vessel A and B of equal volume of 8.21 L are connected by a narrow tube of negligible volume with open valve. The left hand side container is found to contain 3 mole CO2 and 2 mole of He at 400 K. What is the partial pressure of He in vessel B at 400 K?
A capillary tube of radius 0.4 mm is dipped vertically in water. Find up to what height the water will rise in capillary. If the capillary is inclined at an angle of of 60 degree with the vertical, how much length of the capillary is occupied by water? Surface tension of water is 7.0×10 to the power −2N per meter.
A compressed cylinder of gas contains 1.50×103 g of N2 gas at a pressure of 2.0×107 Pa and a temperature of 17.1∘C. What volume of gas has been released into the atmosphere if the final pressure in the cylinder is 1.80×105 Pa ? Assume ideal behaviour and that the gas temperature is unchanged.
A rigid vessel of volume 0.50m3 containing H2 at 20.5∘C and a pressure of 611×103 Pa is connected to a second rigid vessel of volume 0.75m3 containing Ar at 31.2∘C at a pressure of 433×103 Pa. A value separating the two vessels is opened and both are cooled to a temperature of 14.5∘C. What is the final pressure in the vessels?
