Phase changing - Apex
Foil cut into pieces represents a physical change.
Corrosion represents a CHEMICAL change.
A solve dissolves when added to a liquid
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Drying clothes represents a physical change, not a chemical change. The process simply converts liquid water to gaseous water, so it's only a change in state.
The burning of gasoline is a chemical change. The evaporation of gasoline is a physical change. This is a physical change because it is a change in state of matter (from liquid to gas).
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.
Foil cut into pieces represents a physical change.
Corrosion represents a CHEMICAL change.
Spoiled food of any kind represents a CHEMICAL change.
i m pretty sure a colour change represents a Chemical change
For example the transformation of liquid water in vapors (vaporization).
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.
A solve dissolves when added to a liquid
No. Freezing represents a physical change from the liquid to the solid state. The composition of the substance does not change.
Evaporation represents the uptake of energy by the liquid that results in a physical change. (phase or state of matter)
