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.
