Adiabatic electrical Thermodynamics question - Please Help! The question is a thermodynamics question where the system is a resistor in a circuit; the question is as follows: A thermally insulated (Adiabatic) resistor of 30 Ohm's has a current of 2 Amperes passed through it for 1 second. It...

In an Adiabatic Process no heat energy is trasferred into or out of the system so there is no energy change, BUT, there is a change in pressure, volume and temperature. But when atoms or molecules gain/loose heat energy they vibrate more/less respectively. And the measure of the vibration of...

The question is as follows: the partial derivative (given as a partial, but i don't know the notation, so letter d is really little delta for the partial) (du/dT)p = Cp - P(Beta)v where Beta = expansivity coefficient = 1/v (dv/dT)p again, all the "d's" are lowercase delta's for the...

An ideal gas at 500 K is expanded adiabatically to 6.5 times its original volume. Determine its resulting temperature if the gas is as follows. (a) monatomic (b) diatomic (no vibrations) (c) diatomic (molecules do vibrate) Anything to get me started?

Hello Friends! can anybody help me? show that for a quasi static adiabatic process of an ideal gas, the following reaction holds TV^{\gamma-1}}=constant Secondly::: At about 100ms after detonation of a uranium fission bomb, the "ball of fire" cosists of a sphere of gas with a...

Why doesn't an irreversible adiabatic process follow the equation, PV^(gamma)=constant?

I have a question regarding Carnot Cycles and Adiabatic processs. I have cylinder with n moles of a mono-atomic gas with a specific Volume, Pressure and Temperature. This Cylinder is closed by a piston. This system undergoes the four step Carnot Cycle A-B, B-C, C-D and D-A. A-B: Is...

argon enters a turbine at a rate of 800 kg/min, a temp of 800C and a pressure of 1.5MPa. It expands adiabatically as it pushes on the turbine blades and exits at a pressure 300KPa. Calculate its temperature at exit. The equations I am working with are PV^(gamma)=constant and...

Sorry about the repost, but I am frustrated with this problem. An ideal monatomic gas, consisting of 2.47 mol of volume 0.0890 m3, expands adiabatically. The initial and final temperatures are 22.3oC and -64.3oC. What is the final volume of the gas? I've tried solving for P in terms of T...

An ideal monatomic gas, consisting of 2.47 mol of volume 0.0890 m^3, expands adiabatically. The initial and final temperatures are 22.3oC and -64.3oC. What is the final volume of the gas According to a formula in the book, the volume of an ideal monatomic gas' volume expands by 1.52, but I...

This one had three bullets by it so it's a pretty tough one. Work and rambling thoughts so far... please tell me if I'm wrong. This would be a change in entropy problem for the first couple of ratios right? (delta)S=Sfinal-Sinitial=nRln(Vf/Vi)+nCvln(Tf/Ti) yet it is an adiabatic operation...

How do you find the coefficient for a transition from one state to another using the adiabatic theorem? I've looked in a couple different books and their answers are different. Thanks

I have 5.00 mol of O2(Oxygen) at 20.0 Celsius and 1.00atm. I will compress this to 1/10 the original volume. Find the work? The correct answer is 46.1 Kj I am having a terrible time with this. This is what I know: Q = 0 for an adiabatic process, and the change in internal energy is...

Hi there, after years of blissful unawareness, I suddenly managed to find a simple yet, annoyingly perplexing question regarding our old friend, the adiabatic process. Let's look at the facts. Any textbook will tell us that in an adiabatic process no heat is exchanged between the system and...

I have this problem and I do not have the answer, but I get an answer that I feel is probably wrong, so can someone please check my work and point out where I went wrong?? Here is the problem: moles = 0.10 of O_2 T(initial) = 150 C = 423 K P(initial) = 3.0 atm = 303.9 KPa The gas...

A fixed quantity of an ideal monatomic gas (γ = 5/3) is being taken around a cycle p1 = 10 atm V1 = 2 L T1 = 370 K V2 = V3 = 15 L p2= 4/3 Here's what's happening: During the isothermal process, the gas expands while in contact with a large heat reservoir, so its temperature remains...

Hello there! Do you know any good link about the adiabatic theory of perturbations? (theoretical mechanics) thanx!

I'm not sure I understand why the Carnot cycle involves adiabatic processes at all. I can't seem to find a reason. Also on a related note, how exactly does a Carnot heat pump (refrigerator type) work? Is the sequence the same as a Carnot heat engine?

Hi, I just need help getting started on a question.. I'm not even sure where to begin: It is desired to ignite a gas at 1000 degrees celcius by compressing it adiabatically to 27 degrees celcius. a) by what ratio must its volume be changed? I'm not really sure how to approach this...

I've been struggling with this problem for an hour or so now, and can't seem to find the right answer. Perhaps someone here can help? I would be very grateful. ;) Two moles of an ideal gas ( = 1.40) expands slowly and adiabatically from a pressure of 5.09 atm and a volume of 12.7 L to a...
