    Explain Work
AI Thread Summary
To calculate the work involved in expanding a gas from 1.00L at 10.0 atm to 10.0L at 1.0 atm, the formula W=-PΔV is used, but the path of the process is crucial for an accurate answer. The discussion highlights that without knowing how pressure changes with volume, the work done cannot be definitively calculated. Participants emphasize that the problem's assumptions and additional information about the system are necessary for a complete solution. The conversation also questions the level of the course and whether integration techniques are permitted for solving the problem. Ultimately, the lack of specific details about the expansion path leaves the question unanswered.

Calculate the work involved in expanding a gas from an initial state of 1.00L and 10.0 atm of pressure to 10.0L and 1.0 atm pressure.

I know W=-PdeltaV
but I don't understand how they get w=-(1.00atm)(10.0L-5.00L)

Thanks.

anyone?
 
I don't think anyone answered this because the work done is path-dependent, and with the info you've given, it can't be really "answered". Assumably P is a function of V or V is a function of P, depending on how this process was done.

Then what level course is this (are helpers allowed to mention "integration"?) Do you have any other info on the system or the problem's assumptions?

Indeed. You can't answer this question becuase the path isn't given.

Song, are you sure that's exactly how the question was stated?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
