Kinetic energy of a molecule is zero at 0∘C
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:
If Pd vs. P(where P denotes pressure in atm and d denotes density in gm/L ) is plotted for He gas (assume ideal ) at a particular temperature. If [dPd(pd)]P=8.21atm=5, then the temperature wil be
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?
At what temperature most probable speed of SO2 molecule have the same value as root mean square speed of O2 molecules at 300 K?
In a gravity free cabin, a non-conducting liquid of surface tension T and possessing uniform volume charge density p is sprayed into large number of drops. After spraying, the drops float around in the cabin and keep on breaking apart into smaller drops and coalescing into larger drops. While floating, the electrostatic forces between the drops are negligible. Estimate radius of the drops when their number reaches a stable value.
56 g of nitrogen and 96 g of oxygen are mixed isothermaly and at a total pressure of 10 atm. The partial pressures of oxygen and nitrogen (in atm) are respectively :
