Yes, the smell of food spreads without entering the kitchen because of diffusion. The aroma, carried by air particles, travels from the kitchen to surrounding areas, allowing us to detect it without being close.

Yes, the smell of food being cooked spreads through the air due to a process called diffusion. As food is heated, molecules responsible for the aroma mix with air particles. These particles move from the kitchen to other areas, carried by air currents. Our nose detects the scent when these particles reach it, even without entering the kitchen. This is an example of how gases, like aromas, disperse through a medium and can be sensed from a distance.
