Joule free expansion (animation, physics)

This animation shows the Joule expansion of an ideal gas. The speed of the particles stays the same during the expansion which explains why the temperature of the gas remains the same.

initial and final temperature of gas in chamber is same only, otherwise temperature does not remain constant during the process this is because speed of particle does changes , first increases and then decrease

[@lucasherrmann6985]

For this reason it isn't a isotermic process.

[@aryanaryan99899]

​@@lucasherrmann6985first increase (T) and then decrease(T)

[@aryanaryan99899]

​@@lucasherrmann6985he stated that in the end about temp.

What do you use to make the animation?

[@iqraurooj6516]

But my book says: when sudden expansion of gases occurs cooling takes place (Joule Thomson effect)

[@newfiecanadian]

Yeah, what's up with that? Why does an ideal gas not cool upon expansion?

[@iqraurooj6516]

but this video shows that the speed of the particles stays the same during the expansion so the temperature of the gas remains the same.. wasn't it supposed to cool upon expansion?

[@newfiecanadian]

Yeah, I'm confused too. I'll let you know if I find out anything to clarify. :)

[@Wexexx]

It does not cool because in the special case of an ideal gas the Joule Thomson co-efficient is zero. However, if you have a real gas it will indeed cool.

[@iqraurooj6516]

Ohkay. So joule thomson effect is experienced only incase of real gases. Thankyou for the clarification.

So space is fake! research flat earth ;)
