NCERT Solutions for Chapter: Kinetic Theory, Exercise 2: MCQ-II

 ABCDEFGH is a hollow cube made of an insulator (Figure). Face ABCD has positive charge on it. Inside the cube, we have ionized hydrogen. The usual kinetic theory expression for pressure

Diatomic molecules like hydrogen have energies due to both translational as well as rotational motion. The equation in kinetic theory  $PV=\frac{2}{3}E, E$ is

In a diatomic molecule, the rotational energy at a given temperature

Which of the following diagrams depicts ideal gas behaviour?
 

When an ideal gas is compressed adiabatically, its temperature rises: the molecules on the average have more kinetic energy than before. The kinetic energy increases.
