Best answer

Tube is a thermal insulator. The removal of value makes the pressurized air inside the tube come out of the tube suddenly.

There are the conditions suitable for adiabatic change which ensure decrease in temperature during expansion. Thus the air escaping from the cycle tube becomes cool.
