In 1824, a French scientist N.L.Sadi Carnot, suggested an idealized engine which is called the Carnot engine, which has an intimate relation with the second law of thermodynamics. To understand the principle, let us consider an ideal gas taken in a cylinder. The bottom..

Introduction - You have learnt in the earlier chapters that flow of electrons constitutes an electric current and current can be generated from a battery or a generator. Scientists later discovered that there are many other ways of producing the stream of electron..

The word 'Physics' comes from the Greek word 'phusis' meaning 'nature', introduced by the ancient scientist 'Aristotle'. Man has always been fascinated by nature. So, he questioned and sought answers for every phenomena nature could offer. The branch of science which is devoted..

The scope of physics is very large. Physics deals with a wide variety of disciplines such as mechanics, heat and light. Study of mechanics helps us to know the forces involved in the flight of a bird, walk of a man and so on. The study of heat helps us to kn..

Man is surrounded by an ocean of energy. Mankind has tapped only a fraction of it. The most colossal dynamo of all is the sun, an unimaginable vast powerhouse which affects everything on earth. From time immemorial man has learnt to harness this energy. In 100 B.C. Romans used coal as a fuel ..
