No, air also has an atomic structure.
An air freshener is a mixture of many chemical substances, so there is no definitive chemical structure for an air freshener.
Matrix structure
No, the shape of the structure does not affect air pressure. Air pressure is determined by factors such as altitude, temperature, and air density, not the shape of the container holding the air.
The structure in the ear that changes sound waves in the air into vibrations is called the eardrum.
The trachea.
Nose
the air goes through the pharnyx then the trachea and into the lungs
Soil structure affects air by influencing air movement within the soil profile. Good soil structure with well-defined pore spaces promotes better air circulation, allowing for the exchange of gases necessary for plant roots and soil organisms. Conversely, poor soil structure, such as compaction, can restrict air movement and lead to reduced oxygen availability, negatively impacting soil health and plant growth.
