the second law of thermodynamics surroundings

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..

Limitations of First Law of Thermodynamics: Need of Second Law - The first law of thermodynamics is concerned with the conversion of energy from one form to another. It helps us to understand energy transformation in different chemical rea..

Second Law of Thermodynamics - The second law of thermodynamics introduces the concept of entropy and its relation with spontaneous processes. In an isolated system such as mixing of gases, there is no exchange of energy or matter between ..

. The kinetic energy and potential energy associated with the random motion constitute the internal energy. When a body sliding on a surface comes to rest due to friction, the organized motion of the body is converted to random motion of molecules in the body and on the surface. Since we cannot con..

The first law of thermodynamics is concerned with the conversion of energy from one form to another. It helps us to understand energy transformation in different chemical reactions. The basic point of the first law is that all physical and chemical processes take place..

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..
