Question

we can get the smell of perfume sitting serval meters away why

Answer 1

Hey friend,


here is your answer,


When perfume is released from the bottle it quickly changes into vapor. The perfume vapor moves rapidly in all the directions as it is volatile. The kinetic energy of the gas molecules is high and the rate of diffusion is high .Hence, we can get the smell of perfume sitting several meters away.

Hope helps for u and if my answer is useful to you mark as brainliest.

Answer 2

this is because particles of matter (in this case perfume) move continuously and furthermore gaseous particles try to occupy as much space as possible. so, in a room, the evaporated particles spread to occupy all the space available, which is why we can smell it from metres away
