Chemical weathering
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Reacting with vinegar is a chemical property because it involves a chemical change where new substances are formed. The reaction between vinegar (acetic acid) and another substance causes a chemical reaction that alters the composition of the original substances.
Grilling milkfish is a chemical change because the heat causes the proteins in the fish to denature and undergo chemical reactions that change its composition and flavor.

Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
The process is called metamorphism, the alteration of chemical composition or structure due to heat and/or pressure.
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.
Reacting with vinegar is a chemical property because it involves a chemical change where new substances are formed. The reaction between vinegar (acetic acid) and another substance causes a chemical reaction that alters the composition of the original substances.
The melting of ice is a physical change, as it changes from solid to liquid without altering its chemical composition. However, when the melted ice reacts with sodium to form a new compound, it is a chemical change because the chemical composition of the substances involved is altered.
No, melting always is physical.As to the previous answer: reacting gold with an acid is not melting but oxidation.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
