Answer 1

In i

In an incense stick(agarbatti) is lighted in one corner of a room, its fragrance quickly spreads in the entire room because-

1. When an incense stick is burned, the incense inside it evaporates due to the heat.
2. Diffusion causes the vapors to move quickly in all directions.
3. The vapor combines with the air and spreads in the entire room i.e., gases particles are continuously in the state of motion.
4. Thus, diffusion is the method that spreads the fragrance in the entire room, which shows particles of matter are constantly moving.
