A commercial cylinder contains `6.91m^(3)` of `O_(2)` at 15.18 Mpa and`21^(@)C`. The critical constants for `O_(2)` are `T _( C ) = -118.4^(@)C, P_(C )= 50.1 ` atmp.Detemine the reduced pressure and reduced temperature for `O_(2)` under these conditions.

The dielectric constant for H_(2)O at 18^(@)C is

A 34.0 L cylinder contains 212 g O_(2) gas at 27^(@)C. What mass of O_(2) (g) must be released to reduce the pressure to 2.463 atm?

A gas cylinder contains 320 gm of O_(2) at 30 atm and 27^(@)C what mass (in gram) of O_(2) would escape if first the cylinder is heated to 127^(@)C and then valve is held open until the pressure the cylinder become 1 atm ( the temperature being maintained at 127^(@)C ).

If 1L of O_(2) at 15^(@)C and 750 mm pressure contains N molecules, the number of molecules in 2 litre of SO_(2) under the same conditions of temperature and pressure will be

If 1L of O_(2) at 15^(@)C and 750 mm pressure contains N molecules, the number of molecules in 2 litre of SO_(2) under the same conditions of temperature and pressure will be
