Two containers hold an ideal gas at the same temperature and pressure. Both containers hold the same type of gas, but container B has twice the number of particles and twice the volume of container A. The average kinetic energy per molecule in container B is :

A. Twice that for container A

B. The same as that for container A

C. Half that for container A

D. Impossible to determine

Respuesta :

Answer:

B. The same as that for container A

Explanation:

To calculate the average Kinetic Energy per molecule,

[tex]K_{avg} = 3/2 K_{B} T[/tex]

Where [tex]K_{avg}[/tex] is the average kinetic energy per molecule and [tex]K_{B}[/tex] is the Boltzmann constant

From the above equation it is seen that [tex]K_{avg}[/tex] only depends on the temperature of the gas

And since the temperatures of both gases are equal, their average kinetic energy per molecule is the same
