If 'a'  stands for the edge  length of the cubic  systems.  simple cubic, body centred cubic  and face centred  cubic, then the  ratio of radii of the spheres  in these  systems  will be respectively.

A  solid  with high electrical  and thermal conductivity  from the following  is

The edge  length  of face centred  unit cubic cell is  508pm.  If the  radius of the cation is 110pm,  the radius of the  anion is ,

At  which one  of the following  temperature  pressure conditions, the deviation of a gas  from ideal behavior  is  expected  to be  minimum?

At  25^oC  and 730  mm  pressure,  380mL of  dry  oxygen was collected.  If the  temperature  is constant,  what volume  will the oxygen occypy  at 760mm pressure?

Under what  conditions will a pure  sample of an  ideal gas not only  exhibit  a pressure  of 1 atm but  also  a concentration of  1mol  L^-1? (R= 0.082  L  atm  mol^-1 deg^-1).

600cc  of a  gas at a  pressure of 750 mm is compressed tp 500cc.  Taking the   temperature  to remain constant, the increase in pressure is ,

500 ML  of  nirogen at 27^oC  is cooled to -5^oC at the same pressure.  The new  volume   becomes

A  pure  crystalline substance  on being  heated  gradually  first forms a  turbid  liquid at constant  temperature and still at  higher  temperature turbidity completely disappears. The  behaviour is a characteristic of substance forming
