Water is an essential resource that plays a vital role in our daily lives. From drinking and cooking to cleaning and hygiene, water has numerous uses that make it an indispensable part of our daily routines. Here are just a few examples of the many uses of water in our daily lives:
Drinking and cooking: One of the most obvious uses of water is for drinking and cooking. Water is essential for maintaining proper hydration, and it is also used to prepare and cook food.
Cleaning and hygiene: Water is also used for cleaning and maintaining personal hygiene. We use water to wash our hands, brush our teeth, take showers, and wash our clothes.
Agriculture: Water is a vital resource for agriculture, as it is used to irrigate crops and keep them hydrated. Without sufficient water, crops would not be able to grow and thrive.
Industrial uses: Water is also used in a variety of industrial processes, including the production of electricity, the manufacturing of products, and the treatment of waste.
Recreational activities: Water is also used for recreational purposes, such as swimming, boating, and fishing.
Firefighting: Water is an essential resource for fighting fires, as it is used to extinguish flames and prevent the spread of fires.
In conclusion, water has numerous uses in our daily lives that make it an essential resource. From drinking and cooking to cleaning and hygiene, water is an indispensable part of our daily routines. It is important that we use water wisely and conserve this valuable resource for future generations.
Materials Science Overview & Classification
Some well-known elemental metals include copper, iron, aluminum, nickel, cobalt, gold, and titanium. But this is not the real position. They cannot be used, as either they are less in quantity or less in measurement, weight, etc. Example: wood, wall Materials that allow the partial transmission of light through it is known as translucent material. Which, although not directly linked with the production processes, are required for day-to-day smooth and efficient running of the enterprise? These cannot be used in the production unit, because, being defective, damaged beyond use, or because of some other reason they have been rendered unusable.

Materials
Just about everything in the environment is made of either a natural or man-made material that materials science played a role in creating. They are poor conductors of heat and electricity. Diamagnetism This property is caused by an induced magnetic field of the orbital electron. They show properties different from their individual constituents. How do you classify engineering materials? They are hard but malleable and ductile. Material costs are the costs of acquiring of material resources necessary for business.

Engineering materials
Some solids are strong, while some solids may break under force. He must have a thorough knowledge and grasp of the characteristics and behaviours of electrical engineering materials to meet this criteria. It possesses electrical, magnetic, chemical and thermal properties. Within the metal classification are 2 categories for metals and their alloys: ferrous iron containing and nonferrous non-iron containing. Ans: The major classification of crystalline solids are as follows- i. The higher the energy level required to remove the electron from the final orbit, the lower the conductivity and the higher the resistivity.

What is Material
Some of the key properties of materials that are considered for a given application are given below. These materials must not produce toxic substances and must be compatible with body tissues i. According to this theory, the atomic orbitals of metallic atoms form molecular orbitals. These ions are systematically arranged in three-dimensional space. Guidelines For this activity, identify whether the highlighted word in each of the given scenario is a metal, polymer, ceramic , or composite. Polar Molecular Solids In such types of solids, polar molecules with permanent dipole moments are constituent particles.

Classification of Magnetic Materials
Plasticity is the phenomenon opposite to elasticity where the material holds the new shape. In other words, resistance decreases with increase in temperature. Packaging Materials: These include all kinds of wrapping materials, such as paper wood carvings, sawdust, straw, etc. Ionic Solids In an ionic solid, the cations and anions are the constituent particles. What are TLE materials? Conductive materials include silver, copper, aluminum, brass, carbon, and others. However, when an external field is applied, the domains reorient themselves to reinforce the external field and produce a strong internal magnetic field that is along the external field.

Classification of Solids: Types, Properties & Characteristics
Ionic solids are hard, brittle, and have high melting points and very high enthalpy of fusion. The stronger the material, the greater the load it can withstand. Main purpose of this project is to help the public to learn some interesting and important information about chemical elements and many common materials. Raw materials can be direct raw materials, which are directly used in the manufacturing process, such as wood for a chair. The constituents are subjected by the application of heat and consequent cooling.

What are the classification of materials?
But there is a slight difference between the two in respect of their uses. That is, if this band is partially filled or it overlaps with a higher energy unoccupied conduction band, the electrons can flow easily under the influence of the electric field and thus conduct electricity. It is the property due to which material regains its shape and size after the removal of an externally applied force. Therefore, conduction becomes possible even at low temperatures. The gap between the conducting band and the valence band in metals is not very large. The total energy required to detach one electron is directly proportional to the material's resistance. Sometimes unused stocks are mistaken for scrap and unserviceable materials.

Classification of Materials
Materials are the basic matter used in industry to be processed and purified to give other materials or objects to be used. Example: Sponge Materials that possess a shiny surface are known as lustrous material. Machinery and Equipment: All the machinery, both power and hand-driven, such as, presses, lathe machines, typewriters, electric motors, fans, and other machines used in the production and other departments, is classified as such. Materials can be classified into four main groups: metals, polymers, ceramics, and composites. Metallic solids Positive ions in a sea of electrons Metallic bonding Copper, silver, gold, iron Hard, but malleable and ductile Fairly high Conductor in solid and molten states 3.
