They possess the kinetic energy. As the temperature rises, particles move faster. Thus, particles that carry smell of hot sizzling food move faster than the smell of the cold food. Therefore, the smell of hot sizzling food can reach us several metres away, but to get smell from a cold food you have to go close.
Q. Why do we consider air as a matter?
Air is classified as matter because it has mass and takes up space, which is the definition of matter.

Q. Why is smell not considered matter?
Anything that has mass and occupies space is called matter. The smell or odor of a substance is classified as matter. The smell of any substance example perfume is the gaseous form of that substance which our olfactory system can detect even at very low concentrations. Hence, the smell is not considered as a matter.
Q. What is not matter example?
Non-matter includes the light from a torch, the heat from a fire, and the sound of a police siren. You cannot hold, taste, or smell these things. They are not types of matter, but forms of energy. Everything that exists can be classed as either a type of matter or a form of energy.
Q. Is a shadow dark matter?
Many galaxies have a dark matter halo that extends far beyond the galactic plane. Any light sources emitting light (that is then shadowed) would have to be on the opposite side of the galactic disk. Shadows don’t have mass; therefore, dark matter cannot be explained by shadows.
Q. Does shadow world exist?
Recent attempts to construct a superstring theory that unifies all the interactions of nature, including gravity, in a finite anomaly-free quantum theory have led to the speculation that there may exist another form of matter (‘shadow matter’) in the Universe, which only interacts with ‘ordinary matter’ (for example.
Q. Is Shadow have mass?
2 Answers. A shadow is a lack of light. Therefore, a shadow has no mass, for a shadow is not an object or energy. Shadows can go faster than light in certain cases because they are not objects.
Q. Do shadows weigh?
No, shadows themselves have no weight. They cannot be placed on a weighing scale and measured,but they certainly have an effect on an objects weight when they fall. Photons hit an object’s surface similar to a ball hitting on a wall, except this ball is very, very small.
