Question

The motion of gas molecules is mainly_______​

Answer 1

The motion of gas is mainly zig-zag (which is also known as braownian motion).

Brownian motion- The molecules of gases move spontaneously and collide with each other. This motion of molecules in gas is known as brownian motion.

Answer 2

Gas particles move in straight lines until they clash with another body and are in a continual state of random motion.

• Gas particle collisions are entirely elastic; all kinetic energy is preserved when two molecules meet.
• The average kinetic energy of gas molecules is solely proportional to absolute temperature, which means that when the temperature is decreased to absolute zero, all molecular motion ceases.
