for T2: So if I'm not using the second law, the other equation I see T and P in is the ideal gas law. Can I use this even though I can't check the validity of the second state behaving as an ideal gas? P2V2/T2=P1T1/V1 is it appropriate here to use V2 = 2*V1, since I've been told the tanks are...

That's what it sounds like to me. So the 2nd law is where this is headed...

The gas in tank B is expanding, or decreasing in Pressure (so also in Temperature).

Homework Statement Two well-insulated rigid tanks of equal volume, tank A and tank B, are connected via a valve. Tank A is initially empty. Tank B has 2 kg of Argon at 350 K and 5000 kPa. The valve is opened and the Argon fills both tanks. State 2 is the final equilibrium state. The temperature...

Okay, so my original problem statement was: "Two well-‐‐insulated rigid tanks of equal volume, tank A and tank B, are connected via a valve. Tank A is initially empty. Tank B has 2 kg of Argon at 350 K and 5000 kPa. The valve is opened and the Argon fills both tanks. State 2 is the final...

I know it's been a while, but I'm interested in continuing with this problem. I am not familiar with working in moles however, so switching the ideal gas law to PV = ZmRT? In addition, there is no shutting of the valve at the end of my problem. The two tanks reach a final equilibrium state with...

Thanks for talking that through. I figured I was missing at least one position vector. What is the variable T?

I think I see what you're saying. I'm kicking myself for not saving my notebook from my dynamics class. Originally I had aligned the y-axis with the bottom edge of the door, the z axis with the hinge/front edge of the door. The origin being at the front bottom corner. My thought was that I...

New here. :) My name is Cora. I'm a 30yo mechanical engineering student, currently out on internship (Co-op program) in between my junior and senior years. I've been using threads off this forum to supplement my textbooks for years, but just now signed up to be able to post. Glad to be here!

I think I'm having a really big block over a really small hangup, so forgive me. I'm on an internship and this is my first time working with rotations/change of basis in a real world scenario. I'm creating a calculator that gives torque in a door mechanism, after a given roll and pitch of the...
