Are physical and chemical changes simply reversible and non reversible changes?
Chemical changes create new substances and cannot be reversed.Burning paperLighting a matchMixing sugar and waterPhysical changes do not create new substances and can be reversed.Crushing a canTearing paperChopping wood
What is meant by reversible and irreversible action?
Reversible action refers to a process that can be undone or reversed, returning to the original state without any permanent changes. Irreversible action, on the other hand, signifies a process that cannot be undone, resulting in permanent changes or consequences.
Can burning a candle be reversible?
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
Are melting freezing boiling evaporating and condensing always reversible changes?
Melting, freezing, boiling, evaporating, and condensing can be reversible changes as they involve physical processes that involve changes in state of matter. However, other factors such as impurities, pressure, and temperature can also influence whether the changes are reversible or irreversible.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Why phase changes are reversible'?
Phase changes are accompanied with optical contrast and therefore the feasibility of phase.
Why is a phase change only a physical change?
See "Related Questions". Phase changes are reversible by adding or subtracting heat. In many cases chemical changes are not easily reversed.
Explain why a phase changes are a property of an atom?
Because atoms only go through phase changes
What are the reversible effects of adding heat?
The reversible effects of adding heat include changes in temperature, phase transitions (such as melting or boiling), and changes in chemical reactions. These effects can be reversed by removing the heat source or by cooling the system.
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.
What are reversible sols?
Reversible sols are colloidal systems that can easily change their state between sol (dispersed phase in a continuous medium) and gel (semisolid) when subjected to external forces like temperature or pH changes. These systems are commonly used in industries for their ability to undergo reversible transformations.
What chemical reactions are reversible?
All physical changes are reversible.
What chemical changes are reversible?
Chemical changes that involve physical changes, such as melting, boiling, or dissolving, are generally reversible. Reactions involving phase changes or reversible reactions where products can revert back to reactants under certain conditions are reversible. An example is the reaction between water and carbon dioxide to form carbonic acid, which can decompose back into water and carbon dioxide.
Are all physical changes are reversible changes?
Not all physical changes are reversible. Some physical changes, such as breaking a glass or cutting a piece of paper, are irreversible because they result in a permanent change to the material's structure. Reversible changes, like melting ice or boiling water, are changes that can be easily reversed by altering the conditions.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
Are all changes reversible?
no
Is wax is reversible changes..?
No, it is not.
