First Law of Thermodynamics or Law of Conservation of Energy - The total energy in the universe is present either as kinetic energy or as potential energy. For example, the water stored in a dam possesses potential energy by virt..

The total energy in the universe is present either as kinetic energy or as potential energy. For example, the water stored in a dam possesses potential energy by virtue of its height (position). When this water is allowed to fall, its potential ene..

The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics..

It is a common experience that energy cannot be generated without consuming energy of some other kind. If a certain amount of one kind of energy is produced, an equal amount of some other kind of energy disappears so that the total energy of t..

The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics). The first law of thermodynamics is the law of conservation of energy, which says that 'energy..

Let us see what is actually taking place in the following examples: Steam engine- Here the coal burns and the heat due to the combustion of coal converts water into steam and the expansive force exerted by the steam on the piston of the engine moves the locomotive. Hydroelectric power plant- Here w..

If the north pole of the magnet is moved towards the coil, the upper face(U.F) of the magnet acquires the north polarity on closing the key between 2 and ..
