Explain the following :
When an incense stick is lighted in the corner of a room, its fragrance spreads quickly in the entire room.
The rate of diffusion increase when increasing the temperature. Therefore, the particles of the smell of the incense sticks diffuse faster in the air molecules and spread quickly in the entire room.
The particles of gases produced by the burning of incense sticks move rapidly in all directions. They collide with the particles of air present in the room, mix with air and reach every part of the room quickly.
