Question

why wind blows from high pressure to low pressure?

Answer 1

Air pressure is the force exerted per unit of area of surface by the air that is directly above the surface.

High pressure means the density i.e. mass per unit volume of air molecules is higher, similarly low pressure means the density of air molecules is low. To balance this difference the air molecules from high density to low density i.e. from high pressure to low pressure flows thus wind blows.
