Question

Which statement is true according to the kinetic theory?

A.
Molecules of different gases with the same mass and temperature always have the same average density.
B.
Molecules of different gases with the same mass and temperature always have the same average volume.
C.
Molecules of different gases with the same mass and temperature always have the same pressure.
D.
Molecules of different gases with the same mass and temperature always have the same molecular mass.
E.
Molecules of different gases with the same mass and temperature always have the same average kinetic energy.

Answer 1

E.

Molecules of different gases with the same mass and temperature always have the same average kinetic energy.

Step-by-step explanation:

According to the kinetic theory:

The average kinetic energy of gaseous particles is proportional to absolute temperature of all gases at the same temperature and have same kinetic energy
