True or false. Gas particles never touch each other.

Question

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

Answer 1

The correct answer is C. False; gas particles can touch each other when they collide.

While gas particles are generally far apart and move rapidly, they can indeed collide with each other, at which point they can be considered to "touch." However, in the context of gases, they are rarely in constant contact due to the large distances between them compared to liquids and solids.
