When a bag of popcorn is opened in a room, the smell of the popcorn spreads throughout the room over time. Explain why this happens using ideas about particle motion. Be specific and detailed.

Respuesta :

Smells travel through the air by diffusion. Air particles, and the odor particles within the air, move freely in all directions plus odors are constantly moving.

Answer:

The aroma of the popcorn spreads throughout the room gradually due to the presence of air.

Explanation:

The popcorn bag releases an aroma when opened. This aroma then travels through the air due to which the aroma spreads throughout the room.

Note:

If the room was closed, the aroma will remain inside the room. If the room was open, the aroma will also spread beyond the room due to the presence of air.
