Homework Statement
Look at the PV diagram of a system above. (attached) The units for P and V are atmospheric pressure atm and liter L. Process A to B and B to C are straight lines on it.
How much is the work done by the system from A to C in J?
Homework Equations
i know that work...
thanks for the response. yes i think i understand it.
what about this: at a point at the bottem of both tubes (its u-shaped, so the bottem of it is shared) is the pressure greater, same, or less than pressure if both tubes at same level?
i know that pressure depends on depth, but I am...
ok so the open end is exposed to atmospheric pressing down on it, but the closed end is not.
That is why open end will have lower water level than closed end right?
please tell me if this is correct understanding of this?
thanks!
i have another ideal gas law question.
how can we say that a mole of any ideal gas will "occupy" 22.4L , when by definition of ideal gas, they don't occupy any space?
isnt n moles of the gas? If you let 1/2 the gas escape, and half the volume, then P would stay same right?
if you can't change moles of gas, then how many moles of gas in ideal gas?
?
it ends by asking "What is the flaw in the student's reasoning?"
so the statement is wrong in someway, and I quoted it verbatim from the book.
any ideas?
Homework Statement
This question starts by stating.. "a U-shaped tube filled with water is closed on one end. Tube is about 1m tall. When water is removed from the open end, the water level in the closed end doesn't change.."
Then a series of questions..
My question is, why doesn't the...
well, this homework questions says: "explain why the following statement is incorrect"...
"in the ideal gas law, P=nRt/V, so the pressure is inversely proportional to the volume. If you decrease the volume, the pressure has to go up"
That looks pretty correct to me! so i am stumped
Homework Statement
if you have an ideal gas in a syinge, then you compress the syringe to a point, then that means that Volume has decreased. Consequentally, Pressure must increase to compensate (oin order for PV=nRT to be true) right?
I think this is wrong but I am not undersnating why...
