英文物理题
In the simulation, where you had a mixture of equal number of light species (Hydrogen) and heavyspecies (Nitrogen) at a temperature of 300K, was the average speed of lighteror heavier particles greater than the Escape Velocity of Earth?
A. The average speed of lighterspecies was greater than the Escape Velocity of Earth.
B. The average speed of heavierspecies was greater than the Escape Velocity of Earth.
C. Average speed of neither of thespecies were greater than the Escape Velocity of Earth.

英文物理题In the simulation, where you had a mixture of equal number of light species (Hydrogen) and heavyspecies (Nitrogen) at a temperature of 300K, was the average speed of lighteror heavier particles greater than the Escape Velocity of Earth
选C
Escape V of earth is around 11.2km/s
Average speed of H at 300K is about 2.4km/s
Same temperature means same average kinetic energy,nitrogen has higher atomic mass,therefore lower average speed than H under same absolute temperature
所以选C
