Introduction

In mathematics, the word, “sequence” is used in much the same way as it is in ordinary English. When we say that a collection of objects is listed in a sequence, we usually mean that the collection is ordered in such a way that it has an identified first member, second

Introduction

In earlier classes, we have studied linear equations in one and two variables and quadratic equations in one variable. We have seen that the equation x² + 1 = 0 has no real solution as x² + 1 = 0 gives x² = – 1 and square of every real number is non-negative. So, we need to extend the real

Introduction

One key basis for mathematical thinking is deductive reasoning. An informal, and example of deductive reasoning, borrowed from the study of logic, is an argument expressed in three statements:

Introduction

The word ‘trigonometry’ is derived from the Greek words ‘trigon’ and ‘metron’ and it means ‘measuring the sides of a triangle’. The subject was originally developed to solve geometric problems involving triangles. It was studied by sea captains for navigation, surveyor to map out the new lands, by engineers and others.

Introduction

Much of mathematics is about finding a pattern recognisable link between quantities that change. In our daily life, we come across many patterns that characterise relations such as brother and sister, father and son, teacher and student. In mathematics also, we come across many relations such as number m is less than number n, line l is parallel to line m, set A is a subset of set B. In all these, we notice that a relation involves

INTRODUCTION

In the previous Chapter, we studied the motion of objects oscillating in isolation. What happens in a system, which is a collection of such objects? A material medium provides such an example. Here, elastic forces bind the constituents to each other and, therefore, the motion of one affects that of the other. If you drop a little pebble in a pond of still water, the water surface gets disturbed. The disturbance does not remain confined to

INTRODUCTION

We shall study the processes where work is converted into heat and vice versa. In winter, when we rub our palms together, we feel warmer; here work done in rubbing produces the ‘heat’. Conversely, in a steam engine, the ‘heat’ of the steam is used to do useful work in moving the pistons, which in turn rotate the wheels of the train. In physics, we need to define the notions of heat, temperature, work, etc. more carefully.

INTRODUCTION

We all have common-sense notions of heat and temperature. Temperature is a measure of ‘hotness’ of a body. A kettle with boiling water is hotter than a box containing ice. In physics, we need to define the notion of heat, temperature, etc., more carefully. In this chapter, you will learn what heat is and how it is measured, and study the various proceses by which heat flows from one body to another. Along the way, you will find out why blacksmiths heat the iron ring before fitting on the rim of a wooden wheel of a bullock cart and why the wind at the beach often reverses direction after the sun goes down. You will also learn what happens when water boils or freezes, and its temperature does not change during these processes even though a great deal of heat is flowing into or out of it.

INTRODUCTION

We shall study some common physical properties of liquids and gases. Liquids and gases can flow and are therefore, called fluids. It is this property that distinguishes liquids and gases from solids in a basic way. Fluids are everywhere around us. Earth has an envelop of air and two-thirds of its surface is covered with water. Water is not only necessary for our existence; every mammalian body constitute mostly of water. All the processes occurring in living beings including plants are mediated by fluids. Thus understanding the

INTRODUCTION

we studied the rotation of the bodies and then realized that the motion of a body depends on how mass is distributed within the body. We restricted ourselves to simpler situations of rigid bodies. A rigid body generally means a hard solid object having a definite shape and size. But in reality, bodies can be stretched, compressed and bent. Even the appreciably rigid steel bar can be deformed when a

Writing Chemical Equations

A chemical equation is an equation that expresses a chemical reaction using symbolic  representation  of  the  chemical  formulae.  Simply  put:  a  chemical  equation represents  a  chemical  reaction  and  each  molecule  is  represented  by  a  chemical formula  e.g.  H2O  represents  water. The  first  equations  of  the  Oswald  Process  will  be  used  to  explain  how  to read  a  chemical

Factors  afecting  reaction  rates 
Several  factors  afect  the  rate  of  a  reaction. It  is  important  to  know  these factors  so  that  reaction  rates  can  be  controlled,  e.g.  to  improve  product  yields and  efciency  in  industrial  processes:

Redox Reagents 

In  the  reaction  15.1  above,  the  magnesium  is  being  oxidized  by  the  chlorine, and the chlorine is being reduced by the magnesium.  The magnesium undergoes and  the  chlorine  undergoes  reduction. Therefore  Chlorine  is  the  Oxidizing  agent!  An  oxidizing  agent  causes  the other  species  with  which  it  is  reacting  to  be  oxidized.    In  this  process,   the oxidizing  agent  accepts  electrons  and  thus  becomes  reduced.

What  is  organic  chemistry? 
Organic  substances  all  contain  carbon  atoms  and  organic  chemistry  can  therefore  be  thought  of  as  the  chemistry  of  carbon  compounds.    All  organic  compounds also contain hydrogen.  Compounds that contain only C C  and C H bonds  are  also  called  hydrocarbons.   In  addition  to  carbon  and  hydrogen,  organic  compounds  can  also  contain  oxygen,  nitrogen,  sulphur,  phosphorus  and halogen  atoms.  The  main  sources  of  carbon,  and  therefore  organic  compounds, are  fuels  such  as  coal,  petroleum  and  natural  gas.   (NOTE:  If  you're  going  to have  an  essay,  this  fact  could  go  in  the  essay  and  be  left  out  here.)

INTRODUCTION

The terms ‘work’, ‘energy’ and ‘power’ are frequently used in everyday language. A farmer ploughing the field, a construction worker carrying bricks, a student studying for a competitive examination, an artist painting a beautiful landscape, all are said to be working. In physics, however, the word ‘Work’ covers a definite and precise meaning. Somebody who has the capacity to work for 14-16 hours a day is said to have a large stamina or energy. We admire a long distance runner for her stamina or energy. Energy is thus our capacity to do work. In Physics too, the term ‘energy’ is related to work in this sense, but as said above the term ‘work’

INTRODUCTION

In the preceding Chapter, our concern was to describe the motion of a particle in space quantitatively. We saw that uniform motion needs the concept of velocity alone whereas non-uniform motion requires the concept of acceleration in addition. So far, we have not asked the question as to what governs the motion of bodies. In this chapter, we turn to this basic question. Let us first guess the answer based on our common experience. To move a football at rest, someone must kick it. To throw a stone upwards, one has to give it

INTRODUCTION

In the last chapter we developed the concepts of position, displacement, velocity and acceleration that are needed to describe the motion of an object along a straight line. We found that the directional aspect of these quantities can be taken care of by + and – signs, as in one dimension only two directions are possible. But in order to describe motion of an object in two dimensions (a plane) or three dimensions (space), we need to use vectors to describe the abovementioned physical quantities. Therefore, it is first necessary to learn the
