why we cant sense the smell of cold food from a distance and can sense from shorter distances
Devipvu2004:
cold aromatic gases
then also smell is there right???
plzz reply
as incence stick is solid ......1)# rate of diffusion of solid is less as compared to gas 2#) so the unlit incence stick has less diffusion with air molecules so its aroma not go too far from stick 3#) but on the other hand when we light up the incence stick molecules of gas moving faster( gain K.E.) as i said gas molecules diffusion rate is better than solid 4#) as the temperature increses kinetic energy increses too, so diffusion more thats why we smell the aroma of lighted skick at distance
but every cold substances produce aromatic gases
but in less amount as compared to hot
smell comes from every substances whether its hot or cold
certain gas called aromatic gases
but there is a difference in kinetic energy
bata rahe ho ya puch rahe ho

hey mate when the food is cold rate of diffusion of the smell in air is less
but when the food is hot air around it is also heated and the diffusion rate is faster so we can sense it from far
hope it helps you
have a great day ahead

a hot substance's molecules spread faster. Because the food is cold, the molecules don't spread easily and we get the smell only when we are closer to it.
hi
can i ask one doubt
hmm.
yes
wait
it can travel shorter distances that is surrounding the food or some more distance away but it cant travel large distances
