Question:
The molecules of a given mass of a gas have root mean square speeds of 100 m/s at 27oC and 1.00 atmospheric pressure. What will be the root mean square speeds of the molecules of the gas at 127oC and 2.0 atmospheric pressure?
Solution:
Vrms = 100 m/s
T1 = 300 K
T2 = 400 K
Vrms = √3RT/M
V2rms =?
Vrms = 115.4 m/s
