1.why is the air coming out of the tyres of a car cooler than the surrounding air?

Dear student
Air coming out of tyres of the car undergoes adiabatic expansion, which results in loss of energy.
Hence the temperature of air is lesser & feels cooler than the air inside the tyre held at high pressure.
We hope that clarifies your doubt
