Zipping up a zipper is a Physical change , Because Just because you are unzipping it and zipping it back up it is still a zipper and it is not changing the look or the form of how it is!.
A chemical property describes how a substance reacts or changes to form a new substance, such as flammability or reactivity. A physical property, on the other hand, describes characteristics of a substance that can be observed or measured without changing its identity, such as color, density, or melting point.
It is a physical property because the element/compound will change without involving a change in chemical composition.Physical
Barium melts at 725°C. physical or chemical property
The melting point of sulfur at 112°C is a physical property. This property describes how the substance changes from a solid to a liquid state under specific conditions, without any change in its chemical composition.
No, the release of energy when sodium metal reacts with chlorine gas is a chemical property, not a physical property. Chemical properties involve changes in the chemical composition of a substance, while physical properties are characteristics that can be observed without changing the substance's composition.
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
It is a chemical change
Plasticity is a physical property, as it relates to the ability of a material to deform under stress without breaking. It is not a chemical property that involves changes in the chemical composition of a substance.
Lustre is a physical property, because... Look up a few definitions of "chemical property." In every one you will find that it involves chemical reactions, or changes in the identity of a substance. Lustre (shininess) is a property that can be observed without any chemical changes to the substance, so it can't be a chemical property.
Yes, melting point is a physical property, not a chemical property. It is a characteristic of a substance that can help identify and differentiate it from other substances based on how it changes states from solid to liquid.
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
neither physical or changes its property
It is a physical CHANGE, not property. A property of matter is something like inertia.
the properties that change are physical and chemical properties!!! :)
Your SENSE of smell is physical, but smells are created by chemical interactions.
neither physical or changes its property
It's so physical ! Because is a property indepedent of chemical changes.
