Hammering gold into foil is a physical change because the gold does not undergo a change in its chemical composition during the process. The structure and properties of gold are altered physically by being flattened into foil, but its chemical identity remains the same.
Explosiveness is a chemical property because it involves the chemical reaction that results in a rapid release of gas, heat, and pressure. It is not an inherent physical property of the material itself.
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
Physical properties are characteristics that can be observed or measured without changing the composition of the substance. When physical properties are altered, such as when a substance changes state (solid to liquid), the basic chemical composition remains the same, indicating that it is still the same kind of matter.
The change in the crushed can appearance was caused by a physical change. When the can is crushed, the arrangement of its particles is altered, but no new substances are formed.
Yes, a soft cushion undergoes a physical change when it is compressed or reshaped because its form and structure are altered without any change to its chemical composition.
The physical property can be measured and quantified. It includes things like melting point, texture, color... A physical change is when a physical property is altered. The most common example is a change in physical state usually from a temperature change (solid melting to a liquid). A physical change does NOT alter the actual substance. (It's still water just in a different form.) MLZ Carpenter, Ph.D.
i am pretty sure it is a physical property! :)
It is a change of a physical property - for example the variation of temperature.
a physical property
The color change of elemental bromine from red to orange is a physical change. This is because the substance's chemical composition remains the same; only its physical appearance, in this case its color, is altered.
Elasticity is a physical change i believe.
a physical change is a change in any physical property of a substance, not in the substance itself
A physical property is a measurable characteristic of an item that is determined by its appearance. A sentence with it would be "More than one physical property of the substance changed when it became a gas."

It is a physical change.Density is not a chemical property. Instead, it is a physical property.
