ABCDEFGH is hollow cube made of an insulator, Fig. Face ABCD has positive charge on it. Inside the cube, we have ionized hydrogen. The usual kinetic theory expression for pressure A. will be validB. 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. |

Answer» Correct Answer - B::D As face ABCD has positive charge on it and the gas consists of ironzed hydrogen, therefore, isotorpy is lost. The usual expression for pressure on the basis of kinetic theory will not be valid would also experience forces other than the force due to collison with the walls of the container. Choices (b) and (d) are correct. |
