Science 1 Chapter wise Summary:
Chapter 1: Gravitation
Gravitational Force is an universal force which is acting not only on any two bodies on the surface of the Earth but also on any two celestial objects. Every object in the universe attracts every other object with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres. The centripetal force is centre-seeking or the force which is acting towards the centre of The centripetal force between the Sun and the planet Earth is responsible for the revolution of the Earth. It is inversely proportional to the square of the distance between them.Along with this the concept of Kepler law and Newton’s Universal law of Gravitation are explained in brief.
Chapter 2: Periodic Classification of Elements
In this chapter you will learn how the elements are classified as well as arranged on the basis of as well as number. Group of three elements having similar chemical properties are known as Triads. Newlands’ Octaves or Law of Octaves states that When the elements are arranged in an increasing order of their atomic masses, every eighth element has properties similar to those of the first. Mendeleev’s Periodic Law explains properties of elements are periodic functions of their atomic masses. Modern Periodic Law states the properties of elements are a periodic function of their atomic numbers. Furthermore, the Entire Modern Periodic table is divided into four blocks, viz, s-block, p-block, d-block and f-block. In electronic configuration, the atomic radius goes on decreasing while going from left to right within a period & goes on increasing while going down (from top to bottom) in a group.
Chapter 3: Chemical reactions and equations
This chapter explains the various types of chemical reactions like Combination and Decomposition reaction, Displacement and Double Displacement Reaction. Apart from this, Endothermic reactions where energy is absorbed on the other hand, exothermic reactions where energy is released are the key points. Balancing the different types of reaction is the major thing you need to focus on.
Chapter 4: Effects of Electric Current
To sum up, Electric current is the flow of electrons in a conductor or amount of electric charge flowing through a particular cross sectional area in unit time. Moving ahead, you will learn the right hand thumb rule and left hand thumb rule. According to Fleming’s Left hand thumb rule, the left hand’s thumb, index finger and the middle finger are stretched so as to be perpendicular to each other. If the index finger is in the direction of the magnetic field, and the middle finger points in the direction of current, then the direction of the thumb is the direction of force on the conductor.
According to Fleming’s Right hand rule when thumb, index finger and middle finger are stretched in the direction perpendicular to each other then the position of thumb indicates direction of motion of conductor, the index finger indicates direction of magnetic field and middle finger indicates the direction of induced current. Towards the end use of AC and DC generators is something you will study in detail.
Chapter 5: Heat
Heat is one of the forms of energy and can be obtained by transforming any other form of energy. It is one of the important factors on which the change of state depends but the temperature remains constant. The melting and boiling point differs from substance to substance. Specific latent heat of fusion is the amount of heat energy absorbed at constant temperature by unit mass of a solid to convert into liquid phase is called the specific latent heat of fusion. Whereas, latent heat of vapourization refers to the amount of heat energy absorbed at constant temperature during transformation of liquid into gas. Thereafter, the concepts such as humidity, dew points are explained.
Chapter 6: Refraction of light
To summarise, this chapter Light is a source of energy that creates a sensation of vision in human beings. Light travels in straight lines. Further it explains the different types of a spherical mirror, convex and concave. The Mirror formula explains the relationship between the object-distance, focal length of a spherical mirror and image-distance. Moving ahead with refraction, it is the bending of waves when it enters a medium.The LAW of Reflection and Law of Refraction are the most favourite topics of the examiner.
Chapter 7: Lens
A lens is a transparent medium bounded by two surfaces; out of which at least one surface is spherical. A lens having both surfaces spherical, bulging outward, is a convex lens or double convex lens. It is thicker at the centre as compared to its edges. This lens can converge the light incident on it is a converging lens. A lens having both surfaces spherical, bulging inward, is a concave lens or double concave lens. It is thinner at the centre as compared to its edges is diverging lens. The centres of the sphere whose parts form surfaces of the lenses refers to centres of curvature of lenses. Whereas, the imaginary straight line passing through the two centres of curvatures of lens (C) known as the principal axis of the lens. The central point of a lens on the principal axis through which light rays pass without changing their path is the optical centre.
Apart from this, you will learn the functioning of lenses in the human eye, what are the defects of vision along with the corrections, spherical mirrors and lens applications. Don’t forget the most important concept of myopia and hypermetropia. Myopia is short-sightedness whereas hypermetropia is far-sightedness.
Chapter 8: Metallurgy
In this chapter you will learn various properties of metals and non-metals as well as Metalloids. Metals have lustre, they are good conductors of heat and electricity as well as they are ductile. On the other hand, non metals are non ductile, non lustrous as well as bad conductors of heat and electricity. When compounds are formed by the transfer of electrons from metal to a non metal, ionic compounds are formed. Basic metallurgical process, How do metals react with various substances, Corrosion and its prevention are the topics you must study.
Chapter 9: Carbon and its Compounds
In this chapter, you will study some more interesting compounds and their properties. Also, we shall be learning about carbon, an element which is of immense significance to us in both its elemental form and in the combined form. Carbon is a versatile element that forms the basis for all living organisms and many of the things we use. Covalent bonds are formed by the sharing of electrons between two atoms so that both can achieve a completely filled outermost shell. Carbon forms covalent bonds with itself and other elements such as hydrogen, oxygen, sulphur, nitrogen and chlorine. Organic compounds categorises into saturated and unsaturated carbon compounds. Saturated compounds are compounds with only a single bond. Unsaturated carbon compounds are compounds with a double or triple bond. The saturated compounds of carbon and hydrogen are methane, ethane, propane, butane, pentane and hexane.
Chapter 10: Space Missions
The universe consists of vast emptiness called space with unknown boundaries. It comprises millions of galaxies which are clusters of Stars. Astronomy is a branch of Science which deals with the study of all the Celestial or Heavenly bodies in this Universe. Sending spacecraft to outer space to observe objects closely and to understand them. There are different types of artificial satellites; they are : Weather satellites, Communication satellites, Broadcast satellites, Navigational satellites, Military satellites and Earth Observation Satellites. Launching an artificial satellite in orbit around the earth for research and various other useful applications.
