What material is very strong and tough but shows very little elongation as it absorbs energy?
Kevlar
Which factor would be considered when deciding upon a building material?
durability, affordability, performance, all of the above. Answer: All of the above. Durability, affordability, and performance, would all be considered when deciding upon a building material.
What characteristic of a solid is most responsible for their structure?
1)Bonding patterns between atoms: It is one of the most important factors which decides the ultimate physical structure of a particular solid object. The stronger bond pattern means the more solid object.
Which of the following is a property of crystalline solids?
Crystalline solids are anisotropic in nature which means they possess different properties in different directions. Crystalline solid possesses these properties such as sharp melting point, long range order and definite regular geometry. Therefore, options B , C , D are correct.
Which of the following would be classified as amorphous?
Among the given items, the one that would be classified as amorphous is GLASS.
What are 3 categories of properties used to classify solids?
Solids can be classified on the basis of the bonds that hold the atoms or molecules together. This approach categorizes solids as either molecular, covalent, ionic, or metallic.
Is sugar a crystalline solid?
Salt and sugar are both crystalline solids. While crystalline solids are well ordered at the atomic level, with each atom or molecule inhabiting a specific point on a lattice, amorphous solids are disordered at an atomic level, with the atoms or molecules held together in a completely random formation.
Which of the following describes the degree to which molecules of one substance are attracted to the molecules of another substance?
adhesion
Which of the following liquids has the highest surface tension?
The surface tension of water is about 72 mN/m at room temperature which is one of the highest surface tension for liquid. There is only one liquid having higher surface tension and that’s mercury which is a liquid metal with a surface tension of almost 500 mN/m.
Which materials are composed of proteins providing high tensile strength?
Collagen is a particularly abundant fibrous protein that accounts for 25 per cent of all body protein. It has high tensile strength and is found particularly in skin and tendons.
Which of the following is most likely to be found in crystalline form?
Answer Expert Verified. The correct answer is Quartz. It is the only one of these commonly found in crystalline form is quartz. Quartz is a common mineral, Silicon Dioxide, and is found as crystals in many common rock formations.
What determines the size of the crystal?
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Which of the following is most likely to have a crystalline structure rubber wood quartz glass?
wood rubber glass quartz. Quartz is most likely to have a crystalline structure. Quartz is most likely to have a crystalline structure.
When an electric field is applied to a metallic crystal the movement of electrons is?
When an electric field is applied to a metallic crystal, the movement of electrons is random. Metals form giant structures in which electrons in the outer shells of the metal atoms are free to move.
What are the materials for protein?
The individual structural qualities of keratin, silk, elastin, resilin and collagen, as well as these materials’ common characteristics of biocompatibility and biodegradability, all contribute to their presence at the forefront of biomaterials research.
Can proteins function as enzymes?
Some proteins function as enzymes, i.e., proteins that catalyze specific biochemical reactions. Enzymes facilitate biochemical reactions and speed them up enormously, making them as much as a million times faster. A particular cell may have thousands of distinct enzymes catalyzing many different reactions.
What are the six properties of solid materials?
Physical properties include density, porosity, water absorption, thermal conductivity and permeability, whereas mechanical properties are elasticity, plasticity, strength, abrasion, hardness, ductility, brittleness, malleability and toughness.
How many types of solid are there?
Solids can be classified into two types: crystalline and amorphous. Crystalline solids are the most common type of solid.
