試題詳解

5. Which one of the following statements is correct?
(A) For a 1.0-L container of neon gas at STP, its frequency of collision with the container walls will increase when the temperature is decreased to -50°C.
(B) Real gas behaves most ideally when a container volume is relatively small and the gas molecules are moving relatively slow.
(C) For separate 1.0-L gaseous samples of H₂, Xe, Cl₂ and O₂ all at STP, H₂ has the highest average velocity.
(D) For separate 1.0-L gaseous samples of H2 and O2 that all have the same average velocity, O₂ has a lower temperature.
(E) For separate 1.0-L gaseous samples of H₂, Xe, Cl₂ and O₂ all at STP, Xe has the highest average kinetic energy.
