Some physical properties can be reversed back after they have been observed, while others cannot. Properties like temperature, magnetization, and electrical conductivity can often be reversed by changing the conditions that caused them. However, certain irreversible changes may occur due to chemical reactions or physical deformations.
An intensive physical property does not depend on the size of the sample. An example of an intensive physical property is density. An extensive physical property does depend on the size of the sample, such as mass and volume.
Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.
it is certainly not a chemical reaction, and it is still melting something, so it is a physical reaction. it does depend HOW you melt it, but other than that, it is a physical reaction.
Motor oil is a type of lubricant that typically consists of long-chain hydrocarbon molecules. These molecules are held together mainly by weak van der Waals forces, which are a type of non-covalent bonding.

physical propertys do something but dont change.Chemical changes toataly change
The Chefs Catalog has its own website. There you will find all sorts of products any cook would love to use. Also, you can order a physical Chefs Catalog there.

These properties are: luster, malleability, ductility, conductivity, hardness, resilience, elasticity, shear modulus, etc.
what are some examples of propertys
a major component of matter???
is it the way it feels
use the propertys to do an observation

No, melting ice is a chemical change where as carving ice is physical.... Another example is chewing food is physical where as enzymes in your saliva breaking down the food is chemical.
