Homework Statement


An inflated tyre suddenly bursts. As a result of this the temperature of air
(a)increases
(b) decreases
(c) may increase or decrease
(d) remains constant.

Homework Equations




The Attempt at a Solution


The answer in the book is (D) remain constant.

Does it mean air outside the tyre ? (atmosphere)


The air formerly in the tire cools off as it expands, as its pressure energy gets converted to kinetic energy.

The kinetic energy added to the atmosphere increases, raising earth’s atmospheric temperature.

in what way this answer is correct? .

Have you learned about the kinetic model of a gas? The speed of the particles is related to the temperature.

yes K.E=3/2(K T)
and K.E=1/2(mv2)

i am sorry . I am trying to learn Kinetic molecular theory of gases

The air outside got warmer but the air that was inside the tyre got cooler so as a whole there is no change in temperature.
Is it the right discussion?

No. Speed of particles.

PS. I'll quote the source post in future.

speed of particles (that were inside the tyre)
Have you had a course in thermodynamics yet?
No . I am trying to learn it
