Write various statements of the first law of thermodynamics |
| Answer» ANSWER to your question: Plank's statement:-It is in no way possible, either by mechanical, thermal, chemical, or other devices, to obtain perpetual motion, i.e. it is impossible to construct an engine which will work in a cycle and produce continuous work, or kinetic energy, from nothing.Crawford 's statement:-For a given SYSTEM we LET ΔE kin = large-scale mechanical energy, ΔE pot = large-scale potential energy, and ΔE tot =total energy. Münster 's statement: -A somewhat unsatisfactory aspect of Carathéodory's theory is that a consequence of the Second Law must be considered at this point [in the statement of the first law], i.e. that it is not always possible to reach any STATE 2 from any other state 1 by means of an adiabatic process.Hope it helps^_^ | |
