Compare the root mean square speeds of o2 and uf6 at 65 degree celsius

The root mean square speeds of O₂ and UF₆ is 513m/s and 155 m/s respectively.

       Where R is the molar gas constant, T is the temperature and M is the molar mass of gas in Kg.

Molar mass of Oxygen is 32.0 g/mol or 0.032 kg/mol

Temperature = 65 degrees Celsius or 338 K

Molar gas constant = 8.3145 J/k.mol

The molar mass of UF₆ is 352 g/mol or 0.352 kg/mol        

Therefore; the root mean square speeds of O₂ and UF₆ is 513m/s and 155 m/s respectively.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
