Dominance of strong repulsive force among the molecules of the gas whereZ is the compressibility factora) Depends on Z and indicated by Z=1b) Depends on Z and indicated by Z > 1c) Depends on Z and indicated Z < 1d) Its independent on Z

X, Y, Z are the three states of matter . State X has more intermolecular space thanstate Y but less than Z, Z has more K.E at a given temperature than Y and Y hasmore interparticle force of attraction than X. Identify X ,Y, Z. Compare X, Y, Z onthe basis of Compressibility and fluidity

The compressibility factor Z=PV/RT for 1 mol of a real gas is greater than unity at a pressure of 1 atm and 273.15 K. The molar volume of the gas at STP will be :

The value of compressibility factor of van der Waals gas at critical point is?a) 8/27b) 27/8c) 3/8d) I8/3

For an ideal gas*1 point(a) Size of molecules is negligible.(b) There is no force of attraction or repulsion amongst the molecules.(c) It strictly obeys the gas laws.(d) All of the above.

In which of the following pure compounds is hydrogen bonding most likely to be a dominant intermolecular force? A. Dimethyl ether, CH3OCH3 B. Hydrogen bromide, HBr C. Difluoromethane, CH2F2 D. Ammonium iodide, NH4I E. Dimethylamine, (CH3)2NH
