Qualitative evidence of the microscopic nature of gases is shown by an effect called Brownian motion.
This motion, in combination with air currents, is how a smell travels.
No, smell cannot travel on a sound wave. Smell is detected through the olfactory system in the nose, while sound waves are physical vibrations that travel through a medium like air, water, or solids.
Smell travels in all directions in the air, not specifically up or down.
Because your nasal passage is congested. That means the smell cannot travel to your brain.
Smell travels at different speeds depending on the substance and environment. In general, smell can travel at speeds ranging from 1 to 60 miles per hour. Factors that influence the speed of smell include the volatility of the substance, temperature, humidity, and air flow.
They smell, track, travel downwind, jump, and kill.
the molecules from the pie (or other creation) travel through the air and eventually land in your nostrils, thus allowing you to smell food.
No, unlike light or sound, smell does not have a specific speed as it does not travel in the same way through a medium. Smell molecules disperse and are detected by receptors in the nose almost instantaneously after they are released.
feet smell wonderful
Yes, it is possible for your apartment neighbors to detect the smell of you smoking weed, as the odor can travel through shared ventilation systems or walls.
Probably not. "Noise" consists of sound waves, which travel, appropriately enough, at the speed of sound ... something like 340 meters per second. "Smell" consists of molecules or particles that physically travel from the source to your nose. Almost by definition, the speed of the physical particles has to be less than the speed of sound waves in air.
No. Time to flush and sterilize (you can buy chlorine pills) the system.
usually on the roof of the car or bed of the pickup. No one will want to smell you. They can tell.
