... With the above definition, when we add heat to the system, dQ is positive. Conversely dQ is negative when heat is removed from the system. When we compress a system, we expend energy in act of doing so and this energy gets stored in the system or gets converted to heat or both. Examples would be com ...

... One cm3 of an ideal gas under normal conditions contains NL = 2.69 × 1019 atoms, the so-called Loschmidt number. Although one may describe the motion of the atoms with the help of Newton’s equations, direct solution of such a large number of differential equations is impossible. On the other hand, o ...

... Irreversible process is one in which thermal system’s changes cannot be retraced, such as gas expanding to fill a vacuum through an open stopcock. A thermodynamic system can transfer its internal energy by changing the temperature (or phase) of another system of it can use its internal energy to do ...

... A steady decrease in the car’s total mechanical energy occurs because of work being done against the friction between the car’s axles and its bearings and between the car’s wheels and the coaster track.
