Which one of the following is a wrong statement in kinetic theory of gases?

Options

A. The gas molecules are in random motion.
B. The gas molecules are perfect elastic spheres.
C. The volum occupied by the molecules of a gas is negligible.
D. The collision between molecules is inelastic.

Explanation

To determine which statement is wrong in the kinetic theory of gases, let's analyze each statement one by one:

1. **Gas molecules are in random motion.**
- This statement is true. According to the kinetic theory of gases, gas molecules move in all directions and their motion is random.

2. **Gas molecules are perfectly elastic spheres.**
- This statement is also true. In the kinetic theory, gas molecules are often modeled as point particles that collide elastically, meaning that there is no loss of kinetic energy in collisions.
