What is the process allows us to smell food being cooked in another room?

The process that allows us to smell food being cooked in another room is called olfaction. When food is heated, it releases volatile aromatic compounds into the air. These molecules travel through the air and enter our nasal passages when we inhale, where they bind to olfactory receptors. This binding sends signals to the brain, allowing us to perceive the scent of the cooking food from a distance.
