When air (ideal gas) moves from a region of high pressure to a region of low pressure, with no addition or subtraction of heat, it expands.

What is Isothermal expansion of ideal gas?

Isothermal expansion of an ideal gas involves increase in the gas volume at constant temperature. The volume of the gas increases while its pressure decreases.

When air moves from a region of high pressure to a region of low pressure, it is no longer adiabatic (constant pressure).

Thus, when air (ideal gas) moves from a region of high pressure to a region of low pressure, with no addition or subtraction of heat, it expands.
