Question

The motion of particles (molecules) of gas between two successive collisions is an example of________.

• A. circular motion
• B. rectilinear motion
• C. curvilinear motion
• D. periodic motion

Answer 1

The correct option is B

rectilinear motion

The particles of gases and liquids after collision moves in a linear fashion i.e. their motion is rectilinear. After another collision they change their path and the overall motion becomes non rectilinear. Hence, between two successive collisions, the motion is rectilinear.
