Question

smell of perfume spreads rapidly in summer than in winter

Answer 1

Smell of perfume spreads rapidly in summer because the intermolecular force between the particles get charged up and starts moving faster than usual due to the heat present in the atmosphere.

Answer 2

The molecules of the perfume travel slowly in the winter since the temperature is low and the atoms are less active. in the summer the molecules are much more active since it is at a higher temperature. with a higher temperature, the molecules mingle with the atmospheric air quickly which allows the perfume to spread faster in the summer.
