Assertion :Helium shows only positive deviation from ideal behavior at room temperature. Reason :Helium is an inert gas.
If 3.7g of a gas at 25∘C occupies the same volume as 0.814g of hydrogen at 17∘C and at the same pressure, then what is the molecular weight of the gas?
The motion of the ball in the vessel is
The pressure in a bulb dropped from 2000 to 1500mmHg in 47min when the contained oxygen leaked through a small hole. The bulb was then evacuated. A mixture of oxygen and another gas of molecular weight 79 in the molar ratio of 1:1 at a total pressure of 4000mm of mercury was introduced. Find the molar ratio of the two gases remaining in the bulb after a period of 74min.
A liquid will not wet the surface of a solid if the angle of contact is
Equal moles of hydrogen and oxygen gases are placed in a container with a pin-hole through which both can escape. What fraction of the oxygen escapes in the time required for one-half of the hydrogen to escape ?
The equalitative sketches I, II and III given below show the variation of surface tension with molar concentration of three diferent aqueous solutions of KCl,CH3OH and CH3(CH2)11OSO3−Na+ at room temperature. The correct assignment of the sketches is
Assertion :A large force is required to draw apart normally two glass plates enclosing a thin water film. Reason :Water works as glue and sticks two glass plates.
