Is reversible work greater than irreversible work?
The key feature why the irreversible work is smaller than the reversible work is the magnitude of the external pressure against which the irreversible work is done against. If you were to increase the external pressure by a factor of two then the irreversible work would be greater. Why does a reversible process do more work?
What is meant by reversible and irreversible action?
The reversible process is the ideal process which never occurs, while the irreversible process is the natural process that is commonly found in nature. This is an irreversible process. Whereas when water evaporates, it can also be condensed in the form of rains. In science, a process that is not reversible is called irreversible.

What is a reversible change?
All changes in the world are one of the two types – Reversible changes and irreversible changes. A change which can happen backward, that is, can be reversed is called a reversible change. If you keep water in the freezer for some time, it transforms into ice.
What are some examples of reversible changes?
Examples of reversible changes. Melting: Melting is when solid converts into a liquid after heating. Example of melting is turning of ice into water. Freezing: Freezing is when a liquid converts into a solid. Example of freezing is turning of water into ice . Boiling: Boiling is when a liquid converts into a gas.
What are physical changes?
Physical changes are changes that occur in the physical properties of the substance, like shape, size, and nature. Physical changes may or may not be reversible changes. Like, turning of water into ice is an example of reversible changes but growth in height is an irreversible change. Chemical changes are changes that occur in ...
Is cooking an irreversible change?
Cooking: We use heat for cooking, right? Once we cook our eggs, we cannot uncook them. Therefore, cooking is an irreversible change.
Is change constant?
‘Change is constant’. Changes happen all around us, even within us. Most of them are irreversible but some of them are reversible changes. Yes. Let’s learn about reversible changes and irreversible changes and understand the difference between them with a lot of examples.
Is water reversible?
But it can turn back to liquid water after removing from the freezer. Therefore, freezing is an example of reversible changes.
What is a reversible change?
Reversible Changes. Any changes which can be reversed or are a temporary conversion are known as reversible changes. The reactions which are reversible are called reversible reactions. In this reaction, one substance is modified into another form but a new compound is not formed.
What are some examples of reversible reactions?
Few examples are melting of wax, freezing of ice, boiling water which evaporates as steam and condenses back to water. Reactions are an interaction of two or more compounds called reactants to produce a product (s). In a reversible reaction, reactants and products formed are connected by a two-way arrow (⇌). This means reactants can be obtained ...
What is change?
Well in chemistry, change can be explained on physical grounds. Changes are very random or uncertain phenomena, it can be better or worse depending on your view. Every day we see different objects changing around us like melting of ice, cooking of food etc. In some cases, you get back the original substance and in some, you won’t get it back. Some changes are slow while some are fast, some are natural and some are man-made. You will find that many changes are taking place around us for e.g. growing of plants in your balcony, sometimes there is a change in colour and sometimes you will find drying of leaves.
Is a change in color slow or fast?
Some changes are slow while some are fast, some are natural and some are man-made. You will find that many changes are taking place around us for e.g. growing of plants in your balcony, sometimes there is a change in colour and sometimes you will find drying of leaves.
Can reactants be reversed?
Reactants react to form an entirely new compound and cannot be reversed. Heating, burning, mixing, powdering are few processes which cause irreversible changes. A common observable example is the cooking of raw egg which can’t be converted back to its original form.
What are some examples of reversible changes?
Some other examples of reversible changes are knitting a sweater, inflation of the tire, ironing of clothes, boiling of water, melting of wax or butter, rolling a roti dough, heating of milk, etc.
What is it called when a change can be reversed?

i. Ripening fruits is an irreversible change because it is not possible to get back the raw fruits from ripened or mature ones.
Why does cooking food cause irreversible changes?
v. Cooking food causes irreversible changes because we can’t get the ingredients back to their original state after they have been cooked. For example, after a cake is baked using milk, flour, chocolate, milk, etc., we cannot get back the ingredients.
What are the two types of changes that happen around us?
These causes can bring about changes in the shape, size, position, colour, or internal structure of a substance. Changes are of two types and they are Natural changes and Man-made (artificial) changes.
When does a substance change to form a new substance?
A substance changes to form a new substance only when certain agents like heat, light, electricity, force, etc. , are applied . Now, if the agent is causing the change to be removed, then in some cases, the new substance changes the reverse direction to form the original substance. And we say that the change can be reversed or that the change is reversible. If the new substance formed does not undergo reverse change to form the original substance, then we say that change cannot be reversed, or the changes are irreversible.
Is a rubber band reversible?
This means that the change which occurred in the rubber band on stretching has been reversed on releasing. So, the stretching of a rubber band is a reversible change. Similarly, the stretching of spring is also a reversible change.
What is irreversible chemical reaction?
Reversible and irreversible are types of chemical reactions that take place in and around us in our daily lives. It was earlier believed that all chemical reactions were irreversible until French scientist Berthollet proved that some chemical reactions were reversible. There are many differences in reversible and irreversible chemical reactions ...
What is the reaction between two products that result in new products and cannot be converted back into original products?
The reactions between two products that result in new products and cannot be converted back into original products are known as irreversible reactions while reactions in which final products can be converted back to the original products at the left of the chemical equation are termed as reversible reactions. ...
What happens when you burn paper?
Similarly when you burn a piece of paper, you are left with ash and smoke that are different from paper and you cannot get back the original product that was paper. This is thus an irreversible reaction.
Is salt a reversible reaction?
This is nothing but condensed water vapor that evaporates after some time on its own. Thus it is a reversible process. When you mix salt or sugar in water, a solution is formed which is different from water and sugar, but when you heat up the solution so that water evaporates, you can get back sugar or salt thus proving that the reaction is reversible and you can get back the original products of the reaction.
What is Irreversible Cell Injury?
Irreversible cell injury takes place when a cell is subjected to intense stress. Irreversible cell injury results in cell death. This is either caused by apoptosis or necrosis. Apoptosis is the controlled cell death which takes place in response to cell aging. Necrosis is the process of cell death taking place due to a physical, chemical or a biological agent that causes irreversible cell injury.
How can reversible cell injury be brought back to normal?
The above three outcomes of reversible cell injury can be brought back to the normal by providing the necessary homeostatic mechanisms which will remove the respective stresses on the cells.
Can cellular injury be reversed?
This result in abnormal outcomes leading to cellular injury which can either be reversed or complete cell death. Reversible cell injuries can be reversed back to normal while irreversible cell injuries cannot reverse back to normal. This is the difference between reversible and irreversible cell injury.
