True or false. Gas particles never touch each other.

Question

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

Answer 1

The correct answer is:

B. False; gas particles can touch each other when they collide.

Gas particles are typically very far apart and move rapidly, but when they collide, they can come into contact with each other, even if only briefly. However, in the context of ideal gases, the interactions between them are often negligible compared to their kinetic energy.
