Respuesta :
due to the air being compressed in a small space the air is pressurized and when the valve is open it causes a loss in pressure making the air gush out.
If you opened the valve on a bicycle tire, the air inside of the tire will come out and the pressure it exert will be less.
Why does the air filled in a bicycle to keep it tight?
When air is pumped into a bicycle tube, the tube gets inflated due to the air pressure exerted by the collisions of gas molecules in air with the inner walls of the rubber tube. This air pressure makes the tyres feel hard.
What causes air pressure to decrease in tires?
When the temperature cools down, the air within the tire shrinks. In the same way, when the temperature rises, the air within the tire expands.
