Question

How can you use water to compare two fuels?

David Collins · Accepted Answer

question Number one is kind of a strange question. Unless you have some context. This is referring to the first part of this section. How can you use water to compare to fuels? It&#x27;s specifically asking you, How can you use water to compare the heat of combustion or the energy content of two fuels? Having read the first part of this section than that would be a little bit more obvious to do this. What you could do is you could take ethanol and methanol and burn a known amount of ethanol or methanol, well ethanol and methanol, and then use water to absorb the energy content of the two fuels. By measuring the change in temperature of the water, the amount of heat released by the burning fuel should be equal to the heat absorbed by the water, which will be equal to the specific eat of water multiplied by its mass multiplied. By that change in temperature that you would be measuring

So for this question, we need to figure out the differences and similarities between a liquid and a gas, so it always helps to be able to draw them. It&#x27;s always good to know what the particulate model would look like if you could actually shrink yourself down and see all these Adams what it would look like. So there is my container of a liquid, and my container of a gas would look something like that. So what are the similarities? One of the differences? Probably easiest to start with the differences. So a gas has no definite volume, meaning it&#x27;s gonna fill whatever container it&#x27;s in. Ah, Liquid, on the other hand, has a definite volume. If I were to pour 100 milliliters, it&#x27;s going to stay as 100 milliliters regardless of whatever container it&#x27;s, so it&#x27;s got a definite volume. Now let&#x27;s look at, um, similarity. So if we look at a similarity, a liquid will take the shape of its container, take the shape of its container, so it&#x27;ll completely take the shape of the container. Depending on what glass or mug you happen to pour liquid into, it&#x27;ll take the shape of its container. A gas will also take the shape of its container. So the difference here is the volume one has no definite volume and one does have a definite volume. A similarity is they both don&#x27;t have a definite shape. They will always take the shape of their containers.

So this question is about distillation of seawater to obtain drinking water. And so the way that works, in essence, is so if we imagine that we&#x27;ve got this large vessel of water and salt rights, we&#x27;ve got water and salt, and actually, you know what I&#x27;m going to Ah, I&#x27;m gonna lower that water level. So we&#x27;ve got saltwater here. We&#x27;ve got seawater, and what we&#x27;re gonna do is we&#x27;re going to we&#x27;re going to enclose that and we&#x27;re actually going to enclose it with a slanted roof just to make it a little bit easier to see what&#x27;s going on. And we&#x27;ll have this separate container right here for collection. And so what&#x27;s gonna happen is we&#x27;re gonna heat up this water. And so we got some fire. There were heating up the water, and as it heats up, the water begins to boil and evaporates, and the salt that is in the water does not evaporate. So the salt eventually what we&#x27;re gonna get is that salt is not There&#x27;s gonna be so much salt that it can&#x27;t remain dissolved in the water because we&#x27;re decreasing the amount of water, and so the salt eventually is going to kind of settle out on the bottom. But the water, the vapor will rise and eventually get to a point where it condenses. And as it condenses on this slanted roof, what&#x27;s gonna happen is it&#x27;s going to, as we know, with water. It doesn&#x27;t really just drip straight off. Most of the time, what&#x27;s most likely to happen is it&#x27;s going to roll down the surface of the roof. It&#x27;s going to stick to that roof a little bit and then kind of come down the side here. And so we end up getting pure water on this side because the salt was left behind.

So if you had a cup of water and a gallon of water that were at the same temperature, the internal energy would be now dependent on their mess. Since copper water smaller takes, it takes less energy to bring it to the same temperature. So this one has you smaller internal energy. And then, since this one has more mass, it has a larger internal energy. So while the temperature is the same, the internal energies are different because of the mess.

So what are some important uses of water? Um, obviously, plants, animals, fungi, bacteria. We all need water to survive, grow reproduced and an industry. The movement of water is used to turn wheels as well esteem. And this is helpful because water is liquid from zero degrees all the way to 100 degrees. And both of these temperatures are fairly easy to accomplish in normal atmospheric conditions, making it ideal for this kind of work.

in this video, we&#x27;ll discuss the pros and cons of using hydrogen as an energy resource. So I want had enlisted the positive aura pros were using. Hydrogen is an energy resource, and the three big ones that I have found in researching this problem are that hydrogen is abundance. It&#x27;s very abundant elements, um, on planet earth. So that&#x27;s definitely a positive thing. Um, the generation, uh, creating hydrogen gas for fuel does not create any greenhouse gases that would affect our environment so negatively as greenhouse gases do. Basically, we generate water and heat as a byproduct when use hydrogen for fuel. And last but not least, we can produce hydrogen fuel, local re, meaning we don&#x27;t have to import it, uh, from basically halfway around the world as we do our fossil fuels from the Middle East. So those are the three main, um, bonuses. We can call them pros or positive points for using hydrogen as fuel. Now, on the flip side, I went ahead and over the next screen to show you the main big negative downside. Using hydrogen as a fuel source is that in order for us to capture or harness hydrogen gas is fuel winning to hide relies water, and this requires equipment called Electra lies Er&#x27;s And these in and of themselves need fuel to basically start the process. So we need we have some options for that. However, Sometimes we need to go back and use fossil fuels to generate the energy needed for these electoral eyes. Er&#x27;s So I listed the methane, the gasoline, the coal, you know, those are possibly lt&#x27;s we already rely on we&#x27;re trying to get away from. However, research in recent years, um, have sort of gravitated toward other Ah, resource is for, ah, the Electoral Isar. So I listened biomass when title energy. There&#x27;s also last but at least can&#x27;t see it behind their solar energy. So we are looking into, um, some further you more beneficial energy sources where these electoral eyes ear&#x27;s better probably take some time. So those are the benefits or prose and also the cons of using 100 US fuel

Problem 1 Easy Difficulty

How can you use water to compare two fuels?

Answer

In calorimetry water is used to compare fuel. Taking same amount of water and same amount of fuel we can compare them by raise in temperature of water.
