Question

Provide examples to support the claim that phase changes are reversible.

Wilhamena Hobbs · Accepted Answer

Okay, So a good example that shows that face changes are reversible would be water. So we can very easily change water, which would be liquid h 20 into a lice, which would be solid age thio by putting in the freezer. So start out it about 25 degrees Celsius, which is about room temperature. So you have a room temperature, water, and then we changed it the temperature to zero degrees Celsius way. Leave it long enough, it&#x27;s gonna turn into ice. They also notices if you know the winter when it&#x27;s cold outside. If you see a pond or a lake, sometimes the water will freeze if it&#x27;s cold for long enough. But then, when the spring comes and it&#x27;s warm again, temperature rises high enough. We end up with liquid water. So that&#x27;s one example who face change that we see and every day life another one. If we had again started looking water and we heated it up and we ended up with steam Uh huh. On, um, if you wanted to reverse that process or actually see this happen? If you see steam collecting on glass, you know it&#x27;s condensation. What that is is water vapor, which is a gas that&#x27;s cooling off and turning back into water, which is liquid. So there you go. That&#x27;s one example of base change.

Kocian. The processes which of course naturally and are reversible, are mixing off to sample off the same sub stahn to sample off same substance. 2nd 1 is compression or expansion, compression or expansion, for example. It can be in the case off the spring, and the 3rd 1 is current flow 20 resistant through zero resistance. So these are the example that occur in nature, which are reversible processes.

by adding or removing energy, we can move a solid to a liquid to a gas or the opposite a gas, a liquid to a solid. So let&#x27;s think as if we were boiling water on the stove and before whatever reason, we&#x27;re starting off with ice. So first we have solid. And as we apply heat that solid becomes a liquid. It becomes stressed normal water. But as more heat is applied to that water that becomes a gas, it&#x27;s steam coming off so that we have that gas. Let&#x27;s say we put it in the freezer. So what? So, um, energy is being removed, and so it cools down and it becomes water. We leave it in the freezer once again, more energy where he&#x27;d is removed. And now it&#x27;s ice. This is just one example of many different compounds that exhibit this

Matthew Hurlock · Answer

All right, So for this question, we&#x27;re basically asking what is a reversible reaction? So in general, when we talk about reactions, we write them. We typically think about them happening in one direction, because same way that we&#x27;ve read sentences. We think, you know, we write the reaction from left to right. This is the way that it proceeds. And while this is true, it&#x27;s important to remember that some reactions can actually occur in both directions. And technically, all reactions can occur in both directions. It&#x27;s just a matter of how, um efficient. They are occurring in both directions and how readily it is that they&#x27;re going to occur in both directions. In other words, every reaction has a rate at which it happens. And when you have a reaction that&#x27;s reversible, there&#x27;s going to be a reaction rate for the forward reaction. There&#x27;s going to be a reaction rate for the reverse reaction and when something reaches equilibrium, what we say is that the rate of the forward reaction is equal to the rate, the reverse reaction. In other words, the concentrations of the reactions and the products are not changing. If this condition can be met, such that perturbations to one side of the other eventually shifts the reaction back to equilibrium. Constant K. The reaction is said to be reversible, so a reversible reaction in summary is one that can proceed both in the forward and reverse reaction.

David Collins · Answer

There are several things that can be monitored as evidence that a chemical reaction has occurred. Four of them are the production of heat or light, the formation of gas, a change in color or a change in odor.

Kyle Gassaway · Answer

dynamic equilibrium in chemistry is when the individual molecules are changing. But the system as a whole isn&#x27;t changing. So, for instance, let&#x27;s look at a glass of water with ice in it. Now here&#x27;s a glass of water and dries Cube. Now, right where the ice cube is touching the water, you have two things going on. You got your nice lattice in the ice kind of looks something like this. And then you&#x27;ve also got your liquid eyes, which is floating next to it. Kind of like this. That&#x27;s just disorganized. So what&#x27;s going on? Uh, where the solid and the liquid touch is? These water molecules, thes liquid mold molecules, are going to be freezing and joining with the ice. But these solid molecules, we&#x27;re going to be melting, refusing off and joining the liquid water. So in a dynamic equilibrium, even though you have, even though you have individual molecules that are changing the system as a whole is still remaining the same. Staying equal

Problem 3 Easy Difficulty

Provide examples to support the claim that phase changes are reversible.

Answer

Phase changes are reversible depending upon the amount of energy supplied.
Ex. Boiling water: Depending upon the temperature, water can exist in liquid, ice or vapour phases.
