True or false. Gas particles never touch each other.

Question

A.
True; gas particles move too rapidly to ever touch.
B.
True; gas particles are located too far apart to ever touch.
C.
False; gas particles can touch each other when they collide.
D.
False; gas particles are constantly touching each other.

Answer 1

The correct answer is B. True; gas particles are located too far apart to ever touch.

In a gas, particles are generally considered to be far apart compared to the size of the particles themselves, and while they can collide with each other, the concept of "touching" in a classical sense does not apply because of the distances involved and the nature of gas particle movement.
