Answer 1

Answer:-

A bottle of prefume was open in a room. The fragrance of its vapour spreads in the entire room.

Reason:-

A bottle of perfume was open in a room the fragrance of its vapour spreads into the entire room because of Diffusion.

• When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air.

• The particles of smelly gas are free to move quickly in all directions.

• They eventually spread through the whole room from an area of high concentration to an area of low concentration.

The gas is spread all over that room because it can move in all directions due to the collision between molecules.

The fragrance of perfume spread in the room due to the process of diffusion i..e..,mixing of the molecules of any substance in the nature or with air by their own.
