Question

The rms speed of molecules of hydrogen at 27 degrees * C is v. Then the temperature at which the rms speed of hydrogen molecules will be 2v, is
150 K
600 K
1200 K
279 K​

Answer 1

Answer:

The rms speed of hydrogen molecules at 23 °C is 1920 m s–1. The escape velocity from the Earth is 11 000 m s–1. Explain why almost all the molecules of hydrogen that have ever been in the Earth's atmosphere have escaped into space but many oxygen molecules have remained in the atmosphere.
