Phase changing - Apex
A solve dissolves when added to a liquid
Corrosion represents a CHEMICAL change.
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
The chemical formula H2O represents water. It is a chemical formula that describes the composition of a substance, in this case, water. Therefore, it is related to a chemical change rather than a physical change.
Foil cut into pieces represents a physical change.
A solve dissolves when added to a liquid
The burning of gasoline represents a chemical change because it involves a reaction with oxygen to produce heat, light, and new chemical compounds. On the other hand, the evaporation of gasoline represents a physical change as it involves the gasoline changing from a liquid to a gas without any change in its chemical composition.
Toasting bread represents a chemical change.
Tearing paper represents a physical and not a chemical change. Chemical bonds are not broken in this instance, but paper is physically separated (by force) from other paper.
Spoiled food of any kind represents a CHEMICAL change.
i m pretty sure a colour change represents a Chemical change
Slicing turkey represents a physical change, not a chemical change. The chemical composition of the sliced turkey is identical to the chemical composition of the intact turkey. Only a physical change has taken place.
For example the transformation of liquid water in vapors (vaporization).
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
Evaporation represents the uptake of energy by the liquid that results in a physical change. (phase or state of matter)
Peach cobbler represents a dessert.
Corrosion represents a CHEMICAL change.
