MCQ
Which of the following is not an assumption of $\text{KTG}\ ?$
  • A
    Time spent during collision is negligibly small.
  • B
    All gases are made up of molecules moving randomly in all directions.
  • ✓
    Molecules do not collide with each other.
  • D
    Molecules collide elastically with the wall.
✓

Answer

Correct option: C.
Molecules do not collide with each other.
According to $\text{KTG,}$ molecules collide elastically with each other and with the walls of the container. The other given assumptions are true. These assumptions help to develop a model of molecular behavior of an ideal gas.
