Q13.9Multiple correct
ABCDEFGH is a hollow cube made of an insulator (Fig. 13.4). Face ABCD has positve charge on it. Inside the cube, we have ionized hydrogen. The usual kinetic theory expression for pressure
This question refers to a figure in the original PDF.
- (a)will be valid.
- (b)will not be valid since the ions would experience forces other than due to collisions with the walls.
- (c)will not be valid since collisions with walls would not be elastic.
- (d)will not be valid because isotropy is lost. Fig. 13.4 13.10 Diatomic molecules like hydrogen have energies due to both translational as well as rotational motion. From the equation in kinetic theory pV = E , E is Kinetic Theory (a) the total energy per unit volume. (b) only the translational part of energy because rotational energy is very small compared to the translational energy. (c) only the translational part of the energy because during collisions with the wall pressure relates to change in linear momentum. (d) the translational part of the energy because rotational energies of molecules can be of either sign and its average over all the molecules is zero.
