Why is smell not a matter?

Matter:

• The matter is defined as a substance that has mass and can occupy space.
• Solid, liquid, and gas are the three states of matter.

Smell:

• The smell does not fit into any of the classes of matter (solid, liquid, and gas).
• The smell is caused by the diffusion of particles of any solid, liquid, or gaseous substance.
• The smell of any chemical, such as perfume, is the gaseous form of that substance, which the olfactory system can perceive even at extremely low concentrations.
• Therefore, the smell is not a matter.
