Two identical flasks of equal volume are kept at the same temperature. Flask A contains argon (Ar) and flask B contains krypton (Kr). If the pressure inside both flasks is measured to be the same and we assume the gases behave as ideal gases, which answer correctly completes the following statements: (i) The average kinetic energy of the atoms in flask A is the average kinetic energy of the atoms in flask B. (ii) On average, the atoms in flask A are moving than the atoms in flask B.

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
