Let us assume that a system is changing with respect to pressure as well as volume. Let the ‘X’ be the initial state of the system and ‘Y’ is the final state of the system. Now let suppose UX and UY are the energies of ...

Let us suppose that the state of a system changes at constant Pressure. Hence there will be change in volume of the system. Suppose volume changes from V1 to V2 at constant pressure P. Therefore work done w, by the system will be: ...

The energy associated with the disordered, random motion of molecules is called Internal Energy. It is separated in scale from the macroscopic ordered energy associated with moving objects; it refers to the invisible microscopic energy on the atomic and molecular scale. Internal ...

The 1st Law of Thermodynamics tells us that energy is neither created nor destroyed, thus the energy of the universe is a constant. However, energy can certainly be transferred from one part of the universe to another. To work out thermodynamic problems we will need ...

Various forms of Energy are: Heat Energy A heat is defined as a transfer (flow) of thermal energy across certain boundary (for example, from a hot body to cold via the area of their contact. Heat may be defined as energy which moves from an object having ...

Energy is the capacity to do work. Any form of energy can be transformed into another form. Energy has been expressed in several different units such as ergs and calories. At present, the accepted unit of measurement for energy is the SI unit of energy, ...

Intensive Property: An intensive property is a physical property of a system that does not depend on the system size or the amount of material in the system. I.e. An intensive quantity (also intensive variable) is a physical quantity whose value does not depend on the ...

The state of a system in which properties have definite, unchanged values as long as external conditions are unchanged is called an equilibrium state. Thermodynamic Equilibrium takes place when the same temperature exists throughout the system. The states of dynamic equilibrium are dealt by Classical ...
