Question

from thermodynamics the average speed (in km/s) of a N2 molecule in atmosphere at a temperature of 27°C is :​

Answer 1

Answer:

pressure and temperature based on their macroscopic definitions. ... Similarly, if the average velocity of the molecules is higher, the gas pressure is higher. ... The higher the rms speed of air molecules, the faster sound vibrations can be transferred ... Identify the knowns: v is the escape velocity, 11.1 km/s.
