Question

When an inflated tire bursts, the air escaping out?
A) Will get heat up
B) Will be cooled
C) Will not undergoes any in its temperature
D) Will be liquified

Answer 1

Hint: Internal energy inside the tire due to high pressure which causes frequent collision of air molecules within the tire and sudden release will decrease the internal energy in terms of loss of heat.

Complete step by step solution:
The air inside the tube of a vehicle is under high pressure. When tyres burst, air inside comes out from that high pressure to an outside environment which is at low pressure. In this process, it has to travel through a small hole.

According to the principle of Joule-Thomson effect. This says that when a gas at high pressure moves to an area of low pressure via a small hole, the gas cools down.
Secondly point is that When the tyre bursts, there is an adiabatic expansion of air because the pressure of the air inside is sufficiently greater than the atmospheric pressure. During the expansion, the air does some work against the surroundings, therefore, its internal energy decreases, and as such temperature falls.

Therefore option (B) is correct.

Note: An adiabatic process is defined as one of the thermodynamic processes which occur without any heat transfer between the system and the surrounding. Work done is due to the change in the net heat content in the system. Work done is due to the change in its internal energy.
