What are 2 physical properties?
Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
What is the most useful physical property of diamonds?
Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.
What are examples of physical properties?
Examples of physical properties, that are intensive properties:
- boiling point.
- melting point.
How many physical properties are there?
There are two classes of physical properties: An extensive property depends on the sample’s size. Examples of extensive properties are variables such as shape, volume and mass. An intensive property, on the other hand, is one that does not depend on the size or amount of matter in a sample.
Which of the following properties is diamond?
Diamond provides an impressive combination of chemical, physical and mechanical properties: The hardest known material. Low coefficient of friction. High thermal conductivity.
|Young’s Modulus (GPa)||1050|
|Bend Strength (MPa)||850|
|Fracture Toughness K1c (MPa.m0.5)||3.5|
What physical property makes diamonds useful for decoration or jewelry?
Diamond is the hardest known natural material (third-hardest material below aggregated diamond nanorods and ultrahard fullerite), and is the most expensive of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light make it useful for industrial applications and jewelry.
Why is diamond an insulator?
In a diamond, all the four electrons present in the outer shell on each carbon atom are used in covalent bonding, so there are no delocalised electrons present and thus makes the diamond an insulator. Complete answer: … The diamond is an insulator.

Can you shatter a diamond?
To answer the question posed, no, it is not easy to shatter a diamond. But they are breakable if you try hard enough. In fact, despite the enormous evidence of how tough diamonds are, they can still be incredibly fragile. Hitting a diamond at the right spot and the correct angle could cause it to chip.
What are 2 physical changes that could occur with a piece of paper?
Physical and Chemical Changes
- Plain sheet of paper. For example:Tearing a paper is a physical change because when the paper is torn only the appearance of paper is changed. …
- Pieces of paper. 3.No new substance is formed. …
- Burning of paper. For example:The conversion of milk into curd. …
- Ashes of paper.
What are two physical changes examples?
Examples of physical change include changes in the size or shape of matter. Changes of state, for example, from solid to liquid or from liquid to gas, are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.
What are two physical properties of apples and oranges?
Apples can be red or green in color while oranges are well, orange. When touching an apple, the skin is smooth. Touch an orange and it is rough. And finally, these two fruits grow better in different types of climates.
