Question

Is energy transferred to a gas or from a gas when it condenses?

Michelle Pribek · Accepted Answer

So this question is really very much like the last question. Um, it&#x27;s asking if energy is transferred to or from a substance in gaseous form when it condenses, uh, into a liquid and vice versa. Um, so recalling from the previous question Ah, we have inter molecular forces that are holding the particles in a substance closer together in the solid and liquid state. So I have the same diagram. John here have solid on the left liquid in the middle, Gas on the right. Uh, in the solid state, the particles are being held very tightly together by these inter molecular forces or ionic attractions. There&#x27;s very little movement in the particles in the liquid state. These forces have been weakened and they can get a little bit more movement in the particles. They&#x27;re held a little bit less closely together. And then when we moved all the way to the right to the gas, she&#x27;s state. These inter molecular forces or attractions have broken apart, and the individual particles are are moving about independently of each other. Um, they&#x27;re spaced further apart. There. Configuration is much more random than in the siloed or the liquid state. So uh, recalling from our previous question, um, it requires heat to be put into the substance to move from solid to liquid when also to move from liquid to gas. Think of, um, water in solid state. It&#x27;s ice. We heat the substance to melt the ice. Inform liquid, um, liquid water. If we heat the water, it will evaporate in form gas. So the same answer applies here as long as we&#x27;re moving from left to right. In this diagram, energy is being, um, put into or transferred into the substance from the surroundings. So when we move from a liquid to a gas, we have to heat the substance or put energy into the substance in order to change from the liquid phase to the gaseous phase. If we&#x27;re going to go in the opposite direction, we&#x27;re going to condense a gas to make a liquid than the opposite occurs. Energy is transferred from the substance to the surroundings when we condense a gas into the liquid form and there you have it

a slow fluid is accelerating in an aerobatic nozzle. So therefore the kinetic energy off the ploy will be increased. And according to energy conservation law, we know the initial total energy should people final Total energy. So therefore the kinetic energy is actually converted founder Internal energy off the fluid. OK, so therefore, on the kinetic energy is actually from the, uh, internal energy off the fluid. OK, and this is the answer for this question.

there&#x27;s a well on the crunchiness into Sully doesn&#x27;t reserve of energy. So we can easily tell that on the kid Resist energy is energy when it changes into study. When the changes into sorry on, we know that when he changes into vapor, then he captures energy. So basically, for this question, it&#x27;s just that the could release this energy. Okay, so

David Collins · Answer

when the cast is expanding, then it is doing what we call PV work and don&#x27;t e, which is equal to Q plus W W can be replaced by Don&#x27;t V or, as it does court. It&#x27;s replaced by negative P. Delta V. So for this particular question, if no heat is being transferred, then this Q value is zero and Delta E equals negative. P. Delta V and V is always Delta V is always final minus initial. So if it says that the gas is expanding in, the final, volume is going to be greater than the initial volume. And this Delta V will be positive. If Delta V is positive, then because of this negative sign that are Delta E value is negative. If Delta E value is negative than the internal energy system is decreasing when a gas expands with no heat flow

in this question. We&#x27;re looking at how gashes propane is compressed to form liquid protein, which is used as a fuel. So during this process, we see that 15 killer jewels of energy are released. And whereas where does this energy come from? So when we&#x27;re going from a gas to a liquid, our molecules are coming closer together. And when our molecules come closer together, we&#x27;re going to increase our inter molecular forces because our molecules are going to have greater attraction for one another because our particles are going from being far apart to being closer together in the liquid form. And if we&#x27;re essentially forming bonds here, we&#x27;re going to be releasing energy. And we can remember this using Barth with barf. When bonds are broken, energy is absorbed. However, when bonds were formed, energy is released. So here we are, forming greater bonds. Thus, we are releasing energy

So the question is what happens to gas particles when I guess is compressed. So when a gas is compressed, that means the volume is going down. And if the boy was going down, that means there is less based for these particles to move around freely. So therefore ah, so this leads to one second. So since they have less volume or less space to move around freely, this will result in the gas particles close to bump into each other each other more. This is another way to describe and increased what more on this up a little bit. So this will lead to an increase in pressure. And there&#x27;s also a lot of offer This, but we look at PV equals NRT. Pressure and volume are inversely related, so as one goes down, the other has to go up

Problem 4 Easy Difficulty

Is energy transferred to a gas or from a gas when it condenses?

Answer

When a gas condenses heat is transferred from gas to surrounding. In condensation process gas looses energy to change into liquid.
