The compressibility factor for an ideal gas is
10 g of a gas at 1 atm and 273 K occupies 5 litres. The temperature at which the volume becomes double for the same mass of gas at the same pressure is:
A pure crystalline substance on being heated gradually first forms a trubid liquid at constant temperature and still at higher temperature turbidity disappears. The behavious is a characteristic of substance forming
At 27∘C a sample of ammonia gas exerts a pressure of 5.3 atm. What is the pressure when the volume of the gas is reduced to one-tenth of the original value at the same temperature ?
Which relationship does hold for Van der Waals gas under all conditions, where all terms have their usual meaning?
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 certen amount of gas at 2.5∘C and at a pressure of 0.80 atm is kept in a glass vessel. Suppose that the vessel can withstand a pressure of 2.0 atm. How high can you raise the temperature of the gas without bursting the vessel?
