Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
Are all changes in states for element reversible?
Not all changes in states for elements are reversible. Physical changes, such as melting or boiling, are typically reversible, allowing the substance to return to its original state. However, chemical changes, like combustion or rusting, result in new substances and are generally irreversible. Therefore, the reversibility of a state change depends on whether it is a physical or chemical change.
What is an example of reversible chemical changes?
The classical example of a reversible chemical reaction is:2 NaCl + CaCO3 ↔ Na2CO3 + CaCl2
What chemical reactions are reversible?
All physical changes are reversible.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
Are physical and chemical changes simply reversible and non reversible changes?

Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.

Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What Is the difference between physical changes and chemical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Are chemical changes reversible?
I would argue that in theory all chemical changes are reversible. However it is certainly true that considerations of enthalpy and entropy mean that some are totally impractical to reverse.
Would freezing an object be physical change or chemical change?
Physical changes and Chemical changes are both the same - this would be a reversible change.
Can a chemical change be undone?
Some chemical changes are reversible, others are not.
