Question

BE THE FIRST TO BE BRAINLIEST
its said that the cold particles present in cold gases released by cold food cannot travel more distance but in case if the cold particles are released in hot air these particles will get that hot bcoz they are released in hot air as a result kinetic energy increases which increases the rate of diffusion and so we can sense the smell of cold food from a distance then why its said that we cannot sense smell of cold food from a distance why????????? I AM REALLY CONFUSED

Answer 1

If you’ve ever made cookies and left the kitchen door open, you’re probably aware that the aroma spreads throughout the house. It is strongest in the kitchen, where the cookies are baking, a little less in the dining or living room, and least in the upstairs corner bedroom. And if the door is closed in the corner bedroom, the cookie scent is even weaker.

This is a delicious example of diffusion, or the movement of matter from a region of high concentration (the cookie pan in the kitchen) to a region of low concentration (the corner bedroom). This principle of diffusion is fundamental throughout science, from gas exchange in the lungs to the spread of carbon dioxide in theatmosphere to the movement of water from one side of a cell’s plasmamembrane to the other. However, the concept of diffusion is rarely as simple asmolecules moving from one place to another. Temperature, the size of the molecules involved, the distance molecules need to travel, the barriers they may encounter along the way, and other factors all influence the rate at which diffusion takes place.
