Understanding Perfume Diffusion

The video tutorial demonstrates an experiment where a teacher uses a balloon containing perfume to teach students about the diffusion of particles. The balloon is passed around the class, and students are asked if they can smell the perfume. This activity leads to a discussion on how perfume particles spread through the air, illustrating the concept of diffusion.

What is the purpose of the balloon in the experiment?

• To measure the weight of perfume

• To contain the perfume for observation

• To show how perfume evaporates

• To demonstrate the color of perfume

What is the main activity performed with the balloon in the class?

• Inflating the balloon

• Passing the balloon around

• Popping the balloon

• Painting the balloon

What question is asked to the students after passing the balloon?

• Can you see the perfume?

• Can you hear the perfume?

• Can you smell the perfume?

• Can you touch the perfume?

What does the ability to smell the perfume indicate about the particles?

• They are heavier than air

• They spread and mix with air

• They are stationary

• They are visible to the eye

What scientific concept does this experiment help to illustrate?

• Magnetism

• Diffusion

• Photosynthesis

• Gravity
