properties of earth materials

The ultimate source of magnetism is the magnetic dipole moment, associated with an atom due to orbital motion and intrinsic spin. This suggests that all substances possess magnetic property as energy material consists of atoms having electrons revolving around the nucleus...

Magnetisation and Magnetic Intensity - The ultimate source of magnetism is the magnetic dipole moment, associated with an atom due to orbital motion and intrinsic spin. This suggests that all substances possess magnetic property as energy material consists of atoms having electr..

Plaster of Paris is used to set fractured bones due to its setting property on hydration. It is used as a sealant in laboratories. Can be used to make casts for toys, statues, ornaments and decorative items. It is used as a fire proofing material. Used in the manufactur..

Metallurgy is a domain of Material Science and Material Engineering. It is a study of the physical and chemical behavior of metallic elements and their mixtures, called alloys. Metallurgists study the microscopic mechanisms that cause a metal or alloy to behave in the way ..

In the chapter on current electricity, we had learnt about the flow of charges, conditions to produce the flow and how different materials respond to an external electric field. We had seen how materials are classified as conductors and insulators. In this chapter, we will study..

A Stone Falling Towards the EarthIt is clear from the above example that it is this force of attraction that holds our complex universe together, keeps the moon revolving around the Earth and holds all the planets in its orbit around the Sun and it is this force which helps us t..

Fig 4.1 Acceleration produced in the stone is due to the large force of attraction exerted by the Earth It is clear from the above example that it is this force of attraction that holds our complex universe together, keeps the moon revolving around the Earth and holds all the pl..

The blood always remains inside the blood vessels and never comes in direct contact with the cells. The materials enter and exit the blood vessels through the walls. The blood flows in the blood vessels under high pressure such that it reaches all the parts of the body in good time. The ..

Earth's crust is rich in inorganic materials which includes ores, that are used on a large-scale to yield metals such as iron, aluminium, copper, tin, nickel, silver, gold, platinum etc. These minerals are very useful in industrial and technological growth. Some of the met..

'Geo' means earth and 'thermal' means heat. Thus geothermal energy is that heat energy obtained from hot rocks present inside the earth. This heat can be used as a source of energy to produce electricity. You know that the innermost layer of the earth is called the co..
