Reversible
Is melted butter and irreversible change?
Typically, yes. Butter is a mixture of fat and milk solids. Once melted the fats separate from the milk solids. 'Clarified' butter, or ghee, is the separated butter fat, often used in Indian cooking, as a canning sealer, or as a dip for steamed shellfish. Clarified butter, once separated from the milk solids, does not require refrigeration to keep it from going rancid, however, it must be kept cool to maintain its solidity.
Is melting butter a chemical change?
Partly physical, partly chemical. Melted butter has different chemical properties than solid butter. The melting process, as with chocolate, is not reversible. Proteins in the butter can become denatured, and isomerization of lipids to trans fats occurs. Phase change is a common example of physical change, but chemical change also occurs in this case.
Explain how breathing on glassis an example of a reversible change?
Breathing on glass is an example of the reversible change because, the air inside the glass can be breathed in again.
Is butter reversible?
yes
Is an example of a physical change?
Processes that are reversible are physical changes. An example is the melting of ice.
What is a non reversible change?
A reversible change is a change you can make, then put back, however a non-reversible change is a change you can make, then it will be stuck like that
Give an example of a reversible change?
An example of a reversible change is an ice cube meting into water and then changing back to an ice cube again if frozen. Another is chocolate melting when heated and changing back to a solid when cooled.
Is evaporating reversible or irreversible?
Yes, this change is reversible.
Was heated butter in a frying pan a chemical reaction?
No, heating butter in a frying pan is a physical change, not a chemical reaction. The butter changes from solid to liquid due to the increase in temperature, but the molecules of butter themselves remain the same.
Is perfume evaporating a reversible change?
As I have learned, it is an irreversible change, so no its not a reversible change.
A physical change creates a new substance and is not reversible?
Nearly, a physical change creates a substance and this is reversible. For example, ice-water. Water-steam. These are all reversible. A chemical change is irreversible. For example, baking a cake; you cannot get the original ingredients back again.
