Gaseous helium is in thermal equilibrium with liquid helium at 6.4 k. the mass of a helium atom is 6.65 × 10−27 kg and boltzmann’s constant is 1.38066 × 10−23 j/k. determine the most probable speed of a helium atom. answer in units of m/s.

162.78 m/s is the most probable speed of a helium atom.

Explanation:

The most probable speed:

= Boltzmann’s constant =

T = temperature of the gas

m = mass of the gas particle.

Given, m =

T = 6.4 K

Substituting all the given values :

162.78 m/s is the most probable speed of a helium atom.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
