Hardness is a property of substances.
Yes, hardness is a specific property of each material.
The property is hardness.
The hardness of diamond is a physical property of the diamond. The statement is also untrue as diamond is only the hardest known mineral, not the hardest known substance.
Hardness is a physical property that describes the ability of a substance to resist deformation. Ability to react with oxygen is a chemical property that describes how a substance interacts with oxygen. Color is a physical property that describes the visual appearance of a substance. Freezing point is a physical property that indicates the temperature at which a substance changes from a liquid to a solid.
physical property
For example a low hardness or a low melting point.
No natural substance is equal in hardness to a diamond.
Yes, a substance with a hardness of 8 on the Mohs scale will scratch a substance with a hardness of 7. The Mohs scale compares the hardness of minerals, and a substance can scratch any mineral with a lower number on the scale.
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
An example of a substance with high density is lead, which is dense and heavy. Gasoline is an example of a substance with flammability, as it can easily catch fire. Diamond is an example of a substance with hardness, as it is one of the hardest known natural materials. Silver is an example of a substance with luster, as it has a shiny and reflective appearance.
physicalNo. It's a physical property
