Which material is the hardest known material?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
What are the advantages of classification of materials?
Advantages of classification of objects are:
- It makes identification of objects easy.
- It helps in sorting of objects.
- It hels in locating things.
- It helps in understanding similarites and dissimilarites among objects.
- It helps to know about properties of objects easily.
What is the basis of classification of materials?
.. These three classifications are metallic, ceramic and polymeric. Additionally, different materials can be combined to create a compositematerial. Within each of theseclassifications, materials are often further organized into groups based on their chemical composition or certain physical or mechanical properties.
What are the advantages of classification of objects Class 6?
Answer: Following are the benefits of classification: (a) It gives a systematic knowledge of different things. (b) It tells us how different members of different groups differ from each other.
How is classification useful?
Classification is important because it allows scientists to identify, group, and properly name organisms via a standardized system (Linnaeus Taxonomy); based on similarities found in the organisms DNA/RNA (genetics), Adaptations (Evolution), and Embryonic development (Embryology) to other known organisms to better .
What is classification in simple words?

How is classification useful explain with at least two examples?
Classification is the technique which involves arranging the organisms by taking in account some similar features and differences in the organisms. It is useful because : 1. It makes study of the organisms better and easier.
Why is classification an important life skill?
Why is the understanding of classification an important life skill? For organizing all animals and kingdoms of life. So, everyone knows what your talking about and that is the way to organize kingdoms, it’s a common language.
Why do we classify things?
It is necessary to classify organisms because: It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences.
How is classification used in school?
One way in which classification is used at school is the separation of different subjects and subject materials. For instance one day you may go to a math class, while another day you may go to a french class.
What are the characteristics of an ideal classification?

- Comprehensiveness.
- Clarity.
- Homogeneity.
- Suitability.
- Stability.
- Elastic.
What is a good classification system?
A good classification system can help you identify unfamiliar organisms. It also allows you to organize a lot of information, making it easy to find and understand. Taxonomists name and classify organisms based off of characteristics. They put them into groups based on how closely related they are with other organisms.
What are the basic rule of good classification?
A good classification should be flexible. It should have the capacity to accommodate with the new situation. Stability of classification does not mean rigidity of classes. The term stability is used in a relative sense.
What are examples of classification?
The definition of classifying is categorizing something or someone into a certain group or system based on certain characteristics. An example of classifying is assigning plants or animals into a kingdom and species. An example of classifying is designating some papers as “Secret” or “Confidential.”
