Hi everyone, I have a fundamental question to the first part of Swendsen's Intro to StatMech and Thermodynamics (book). Suppose we have two isolated systems of volumes ##V_1## and ##V_2##. We distribute ##N## ideal gas particles across the two systems with total energy ##E##. Suppose we bring...

We know linear spring force F = kx(t), k = spring constant, during any moment t of energy release. displacement x(t) = ʃv(t)dt the power p = F*V = kx(t)v(t)= kv(t)* ʃv(t)dt My question: Is there a mathematical function of special v(t) to make power p constant?

Fermilab's E989 experiment is conducting the first precision measurement of the anomalous magnetic moment of the muon (muon g-2) since the Brookhaven lab did so fifteen years ago. It is currently collecting Run-3 data for this experiment, and said that it would be releasing preliminary Run-1...

If there was no atmosphere and a point mass was released at the 45th parallel and able to counteract the centripetal force of gravity (hovering 10ft off the surface), how long would it take before it ended up at the equator.

I'm going to hire a ME to do this but I first want to know whether it is at all doable, exactly what is needed here and what design specifically has to be requested. Here's a sketch of the desired device: Proportionally and size-wise it shoud be similar to a pen. Rotation should be around 10...

Hi. We know that bond formation releases energy and bond break absorbs energy. I still don't figure out why ATP hydrolysis (that breaks a bond between oxygen and phosphorous) releases energy, and it releases a LOT.

In process of releasing heat of nuclear reaction and burning oil, the internal energy of the material(that be burned) be contant if we prevent heat transfer to environment.The temperature of the material increase.How is entropy of the material varied(if we keep volume be constant)?If the entropy...

First of, I have no idea what I'm supposed to do with the neutrinos and the photons. Can somebody explain how to handle these? The rest of what I tried is quite straight forward $$\begin{align*}\Delta E &= 4M_p - M_{He} - 2 M_e + E_{\text{Neutrino and Photons}}\\&= 4M_p - (2[M_p+M_n]-E_B) - 2...

Hello I read several articles about controlled drug release from patches, liposomes, etc Can you tell me please which methods are available to control the release of a drug and what can trigger this release? I am interested in developed available technologies rather that something...

Homework Statement Solid sodium bicarbonate decompose when it's heated above 50 celsius. However, when it is dissolved in water interactions of components changes. So what happens when sodium hydrogen carbonate solution is heated? Does it release carbon dioxide when temperature is above 50...

So I was trying to debunk a conspiracy theory involving bombs and I realized that I have a small problem with Einstein's equation: E=mc2 To be honest I haven't really understood how it's used... I mean, how far should the fission go until as much energy as E=mc2 is released? Does the matter have...

Today, I turned on an electric kettle for heating up some water, then I going to did something else. Since the cover of the kettle was lost, it didn't automatically stop when boils, and I forgot to turn off the kettle when boiled, then all the water vaporized at last and the kettle stopped...

So I was wondering why do nucleons need to remove mass to form a nucleus. Is it because it lowers the energy of the nucleus making it more stable or something completely different. I understand that it is the energy input to break the nucleus into its components, however, why do nuclear reaction...

If I have a container filled with oxygen and hydrogen and heat it up, it would react and create water and heat. Why was heat released? What happens in chemical reactions at a microscopic level that makes it release energy in the form of heat?

Hey people, I have a pressure vessel pressurized to say 20MPa at 33C, of which I'm working with a gas (scCO2 to be exact) which will then be released into the atmosphere (standard pressure and temperature) through a release valve; I'm wondering how long it will take for the pressure to reach...

After an electron absorbs a photon, it will move to a higher energy state. It then releases a photon and returns to its ground state. But why does the electron release the photon? Why does it not remain in that energy state? What forces it to return to ground state?

There is a dispute going on in one of the cities (which will remain nameless for this question, so as not to get political) on the Mediterranean about the following: there are about 120 thousand tonnes of ammonia imported by ship to this city every year (mostly for the production of fertilizer)...

I'm having real trouble understanding some concepts in RLC circuits. If I have a circuit like this. The effective voltage is 120 V. What is the required frequency for resistor to release power of 250 W? I want to really understand this on a deeper level so please make the explanation...

I am working on a mechanism which controls the release of energy while remaining energy efficient. An image of the concept is shown below. (The image is meant simply to get an idea of how it would work- it is by no means perfect). A source of energy (from a spring being released, for example)...

Life on Earth started approximately 3.5 billion years ago. On Earth's surface there was a finite quantity of carbon, among other finite building blocks of life. Organisms absorb this carbon, then they die. After death the organisms carbon (and other life essential ingredients) are released and...

So, as far as I know free electrons are just electrons that have been 'released' from the shell of an atom and can now move. If this is true, what is it that causes the electron to become free in the first place? Thanks in advance to any answers ☺

Hey everyone can anyone tell me how much energy is released (joules) if you take 1 liter of water at 100C and drop it down to 25C (room temp, reg pressure)? Is it significant amount? Better even how much energy is released (approximately) for every 1c drop in temp? Is the release in energy...

Hello all and thanks from advance, 1.I'm looking for a certain kind of material for a project of mine that can quickly absorb heat and in the same time quickly realesing (I guess that's the right term) heat. Of course it's all based on diffrent parameters, but I'm sure there is a better...

I just wanted to ask a question, since it went through my mind after hearing about 'gravitational waves' after they have now, apparently, been identified. does everything realease gravitational waves when it collides? Since everything with a mass has gravity, wouldn't that mean that even when...

I built just a long pendulum in my house in order to start looking at a simple Foucault pendulum "prove the Earth moves" event at the science museum I'm helping to start here in Pensacola. It gave me a nicely reliable movement that seemed to show the pattern I was looking for. Every time, it...

Homework Statement Been looking but can't seem to find any comprehensive help on this. In the Hydrogen atom, what energy is associated with these electron energy transitions: a) N = infinity to N=2? b) N = infinity to N=3? c) N = 4 to N=2? d) N = 5 to N=6? I don't have any relevant formulas...

I believe I can explain why there is energy needed to break intermoleculares bonds and getting into a gas or liquid, but the other way around confuses me. Bonds have potential energy associated to it, so It's needed work to break the bonds, because we would be trying to move a molecule away from...

How to calculate volume of oil spill release from a pinhole of pipeline? I don't find anything about applicable method to solve this case (pinhole leakage), i just find calculation of pipeline rupture Thank You

Hello, We know when there's formation of bonds during chemical reaction there's heat release to the surrounding due to conservation of energy. But what I am confused about, is the kinetic energy of the surrounding increase or the kinetic energy of the atoms that made the bonds increase? if it...
