Worked Solution & Example Answer:Which statement is true about an experiment where Brownian motion is demonstrated using smoke particles in air? A - AQA - A-Level Physics - Question 11 - 2020 - Paper 2
Step 1
Identify the correct statement
Answer
The correct statement regarding Brownian motion is:
C. The motion is caused by collisions between air molecules and smoke particles.
In this experiment, smoke particles are subjected to the chaotic movement of air molecules, which leads to the observable Brownian motion of the smoke.
