Problem of Energy and the Second Law of Thermodynamics

Abstract

Receipt of heat in a thermodynamic system is defined by a Pfaffian form. For the heat-insulated systems it is equal to zero. Cooling of such system as a result of cyclic change of external parameters is usually considered to be impossible. It is offered to carry out full transformation of heat of the environment to work by means of thermally heterogeneous converter containing two gases with different thermal capacities divided by a mobile heatimpenetrable partition. As a result of cyclic change of external parameters along with production of work one gas is cooled, and another — heats up. The possibility of this process is caused by the fact that the entropy of a multiple parameter system cannot be generally defined.
