Question

After discovering that your bike tire has too much air inside, you push on the valve to release some air. If you could measure the temperature of that escaping air, what would you expect to notice as the air is released?

Answer 1

I think this is asking about Charles' Law?

V1/T1 = V2/T2, so as volume decreases temperature decreases; as volume increases temperature increases

apply this logic to your problem - when the air is escaping the tire, is the volume increasing or decreasing? and what does that mean for the temperature?
