For a real gas `'G' Z gt1` as `STP` Then for `'G' :`
Which of the following is true `:`

One of the important approach to the study of real gases involves the analysis of parameter Z called the compressibility factor Z = (PV_(m))/(RT) where P is pressure, V_(m) is molar volume, T is absolute temperature and R is the universal gas constant. such a relation can also be expressed as Z = ((V_(m)real)/(V_(m)ideal)) (where V_(m ideal) and V_(m real) are the molar volume for ideal and real gas respectively). Gas corresponding Z lt 1 have attractive forces amoung constituent particles. As the pressure is lowered or temperature is increased the value of Z approaches 1. (reaching the ideal behaviour) For a real gas G Z gt 1 at STP Then for 'G': Which of the following is true:

When 1 g of gas A at 4 bar pressure is added to 2g of gas B, the total pressure inside the container becomes 6 bar. Which of the following is true-

One litre of an unknown gas weight 1.25 g at STP. Which one of the following can be the formula for the gas ?

For all real numbers x, let the function g be defined by g(x)=p(x-h)^(2)+k , wher p, h and k are constants with p, k gt0 . Which of the following CANNOT be true?

If z is a complex number such that -pi//2lt=a r g zlt=pi//2, then which of the following inequality is true? (a) |z- z |lt=|z|(a r g z-a r g z ) b. |z- z |geq|z|(a r g z-a r g z ) c. |z- z |<(a r g z-a r g z ) d. none of these

If the sides a, b, c, of a triangle ABC form successive terms of G.P.with common ratio r(gt1) then which of the following is correct ?
