Answer 1:
Is odor classified as a physical property?
This might be simply as matter of
convenience.
It is now
well known that different molecules have one of
several smells. The sensation of smell is produced
when the odor-causing molecule binds to certain
sites (called receptors) high up in the nose.
To a large extent, it is believed that the shapes
of molecules control how they smell. This is a
very active area of research worldwide.
