It's a physical change.
You can turn it back to its original state, and the substance's identity is the same.
(ex: water vapor and ice are still H2O)
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
melting ice a physical change
melting any metal is physical. rusting iron is chemical
Melting of gold for jewellery making is a physical change as no new substance is formed after melting. Changes in state or phase are physical 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.
Melting and boiling are physical changes.
The physical and chemical properties, and chemical composition, are not changed after a physical change.
Melting, freezing, and boiling are physical changes, as they do not involve a change in the chemical composition of the substance.
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
Physical - Breaking of glass Boiling of water Melting of ice Cutting of vegetables Chemical - Burning of paper Cooking of food Rusting of iron Souring milk
Freezing (melting, boiling, condensing) are always phycal changes (of matter)
No, melting is never chemical! Neither is boiling, freezing, etc. Those are changes of 'the STATE of matter' and purely physical.
Examples of physical changes include melting of ice, boiling of water, cutting a piece of paper, breaking a glass, and dissolving salt in water. These changes alter the form or appearance of a substance without changing its chemical composition.
