Adiabatic Process: Burst Tire & Cloud Formation

Click For Summary
SUMMARY

The discussion clarifies that both the rapid escape of air from a burst tire and cloud formation are examples of adiabatic processes, where no heat enters or leaves the system. In these scenarios, the air expands rapidly, causing a decrease in temperature as internal heat energy is used for expansion work against external pressure. This cooling effect occurs because heat transfer requires time, leading to the air becoming cooler than its surroundings. In cloud formation, this cooling results in the air dropping below the dew point, causing water vapor to condense and form clouds.

how is the rapid escape of air from a burst tyre and cloud formation in atmosphere an example of adiabatic process?
please explain
 
Science news on Phys.org
What do you understand by an adiabatic process?
 
A process in which no heat enters or leaves the system ?
 
I know in this process a gas expands or is made to get compressed very rapidly as the flow of heat requires finite time .. but am getting a bit confused with these 2 examples ?
on what basis have they been regarded adiabatic?
 
Yes its to do with speed of heat transfer and also the question of where will the heat go?

The second question is the significant one.

In both cases the air expands and cools as it expands because some of its internal heat energy goes to do the work of expansion against the external (air) pressure.

The expanding air becomes cooler than the surrounding air because heat does not have time to transfer. Eventually the temperatures will equalise.

In the case of the cloud formation the air cools sufficiently to drop below the local dew point and so some water vapour condenses out to form the cloud.
