    How can I find the adiabatic equation for real gases?

    I got an equation to solve for this, maybe anyone could help : n Cv dT + an/V + nRT logV/ logbn = 0 How to get exact equation for adiabatic process from this ?

    Temperature and pressure in sauna?

    So you're saying that after I had poured the water, pressure did not change?

    Problem with Thermodynamics. Period dependence on temparature.

    So making simple mathematics, what result I should get ? Maybe, you could look at my calculations: F= 2Ac2dx c2 = KA^(1-?) (2/L^2)^? F= 2K A^(2-?) (2/L^2)^? dx So period formula looks like this: T= 2 ? sqrt( m1/k) k= 2K^(2-?) (2/L^2)^? T = 2 ? sqrt ( A^? m1 (L^?)^2/...

    Problem with Thermodynamics. Period dependence on temparature.

    Thank you for a detailed answer, but since given data include V and length of piston d I'm not so sure, if I can get exact result in those data. Maybe, you could suggest something?

    Problem with Thermodynamics. Period dependence on temparature.

    I'm really sorry for my questions, but I didn't get, how to get exact answer for Periods depence on temperature ( T(T) ). Maybe, if I don't ask you too much, you could give me another hint.

    Problem with Thermodynamics. Period dependence on temparature.

    Sorry, but I didn't get it, how to get f(x) function, when we have f(dx) ? Or maybe it's possible to calculate period with this function?

    Problem with Thermodynamics. Period dependence on temparature.

    Homework Statement http://img267.imageshack.us/img267/5830/80849533.jpg Picture. The volume of that cylinder is V = 1l. In that cylinder we have 1g of hydrogen m=0,001 kg. The cylinder is separated in two equal parts with m1=0,005 kg and d=0.006m length piston. Imagine that we pushed that...

    How can I find the adiabatic equation for real gases?

    Hey! Maybe anyone knows, how to get real gas adiabatic equation. It's not a big deal, when you need to get ideal gas equation, but I haven't got any ideas about real gas. I'm wondering maybe it's something with Van der Waals equation, but in my opinion it can't be like this ...

    Temperature and pressure in sauna?

    Imagine that I pour a bowl of water onto the stones in sauna. So, the problem is that I need to estimate how much did the pressure and the temperature change in cause of this action. Detailed answer would be very appreciated. My attempt : pressure and temperature would decrease, because...

    Thermodynamics question. In Dewar flask liquid nitrogen.

    Homework Statement The problem is that we need to calculate, how much time it takes for nitrogen to evaporate. Given data: dewar flask is in a room, where is T= 293K temperature; In such flask m=0,2 kg of Hydrogen would evaporate in t= 3600s. Also there is given boiling point temperatures for...
