Yes ok I know I look really silly. But doesnt that give me an answer of 13. And so with a starting temp of 300 i assumed i must have done it wrong?

Yes I have read that page 10 times but the equations I dont understand

Ok Thankyou Sir. I will now try and put that together. I have found the k value to be 1.67 so if I use kelvin value of 300, and pressure value of 100kpa assuming the balloon is just submerged, is that correct? And a starting vol of 0.6243m3 P2 would be 200kpa for a depth of 10m T2 =...

Latexman, I have used a the adiabatic equation but I can only work out what happens if I change the volume from 1 value to another with a starting temp. I get out final temp and final pressure. I cant work out how to do it so I have starting pressure and final pressure, what the vol and temp...

Yes looking at it your right, it does sound homeworky, but it's not, it is for a potential energy storage solution and I cant say much more than that really. My only option is to actually do this and record the temp and pressure as I can't figure the maths out, it is beyond me and I dont mind...

Sorry just to say that this question is out of my field and it is for a personal project/prototype I am creating. Thanks

Hello, I am struggling with a problem and will be so grateful if somebody can help after weeks of trying! This is the scenario, please consider a reversible Adiabatic process, If I have an insulated balloon filled with 1kg or 25.03 moles of Argon gas then at 100kpa I make the volume to be...
