Adiabatic Process: Burst Tire & Cloud Formation

AI Thread Summary
An adiabatic process occurs when a gas expands or compresses rapidly without heat exchange with its surroundings. In the case of a burst tire, the rapid escape of air leads to cooling as the internal heat energy is used for expansion against external pressure. Similarly, in cloud formation, air expands and cools quickly, dropping below the dew point, causing water vapor to condense into clouds. Both examples illustrate that the speed of the process prevents heat transfer, resulting in cooler air. Ultimately, the key factor in these scenarios is the rapid expansion that leads to a temperature drop before heat can equalize.

how is the rapid escape of air from a burst tyre and cloud formation in atmosphere an example of adiabatic process?
please explain

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.

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
