second law of thermodynamics creation

Law of Conservation of Energy - 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 the Universe re..

. When the piston is pushed slowly to compress the gas, the gas molecule collides with the piston coming towards it and the speed of the molecule increases on collision (assuming elastic collision, v 2 = v 1 + 2u in the figure below). This way the internal energy of the molecule..

Introduction - The branch of chemistry, which deals with energy changes during various physical processes and chemical reactions, is called chemical energetic..

The 'zeroth law' states that 'if two bodies (say A and B) are in thermal equilibrium with another body C, then the bodies A and B will also be in thermal equilibrium with each other'. This law is important as it helps in understanding the concept of temperature. This means that ..

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 virtue of its height (position). When this w..

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 energy gets converted into kinetic energy. Falling wat..

The above discussion forms the basis of the second law of thermodynamics. This states that the entropy of the universe always increases in the course of every spontaneous (natural) change. Thus, combining the first and second laws of thermodyn..

Absolute Entropies and Third Law of Thermodynamics - The third law of thermodynamics deals with the entropies of the perfect crystalline substances at absolute zero of temperature. According to third law of thermodynamics: At absolute zero..
