The rate of diffusion of a gas is………….proportional to both ……….. And square root of molecular mass.
A box of 1 L capacity is divided into two equal compartments by a thin partition which are filled with 2g H2 and 16 gCH4 respectively. The pressure in each compartment is reorded as P atm. The total pressure when partition is removed will be:
The vapour pressure of water at 80∘C is 355 mm of Hg. 1 L vessel contains O2 at 80∘C, which is saturated with water and the total pressure being 760 mm of Hg. The contents of the vessel were pumped into 0.3 L vessel at the same temperature. What is the partial presure of O2?
A bulb of constant volume is attached to a manometer tube open at other end as shown in figure. The manometer is filled with a liquid of density (1/3)rd that of mercury. Initially h was 228 cm.
Through a small hole in the bulb gas leaked assuming pressure decreases as dtdP=−kp.If value of h is 114 cm after 14 minutes, what is the value of k (in hour−1)?
[ Use : In (4/3) =0.28 and density of Hg =13.6 g/mL.].
A high-altitude balloon is filled with 1.41×104L of hydrogen at a temperature of 21∘C and a pressure of 745 torr. What is the volume of the balloon at a height of 20 km, where the temperature is −48∘C and the pressure is 63.1 torr?
