यदि किसी निश्चित तापमान पर गैस के अणु की सबसे संभाव्य चाल (most probable velocity) 300 m/s है, तो इसकी वर्ग माध्य मूल (RMS) चाल क्या होगी?

A flask contains argon and chlorine gas mixture. The temperature of the mixture is 27 °C. The ratio of the root mean square speed of the molecules of the two gases vrms(Ar)vrms(Cl2) is: (Atomic mass of argon = 40.0 u and molecular mass of chlorine = 70.0 u)

If the root mean square speed of oxygen molecules at 300 K is approximately 483 m/s, what is the rms speed at 1200 K?
