A n2 molecule at 20 c is released at sea level to travel, Ask an Expert

Academics

A N2 molecule at 20 C is released at sea level to travel upward. Assuming that the temperature is constant and that the molecules do not collide with other molecules, how far would it travel (in meters) before coming to rest? To calculate the altitude, h, the molecule will travel, equate its kinetic energy with the potential energy, mgh, where m is the mass and g is the acceleration due to gravity (9.81 m s^-2).
