Boyer department of physics, city college of the city university of new york abstract although plancks constant h is currently regarded as the elementary quantum of action appearing in. While this strategy has a large domain of validity, it can not be justified in the quantum gravity era where curvature and matter densities are of planck scale. The kelvin planck statement or the heat engine statement of the second law of thermodynamics states that it is impossible to devise a cyclically operating heat engine, the effect of which is to absorb energy in the form of heat from a single thermal reservoir and to deliver an equivalent amount of work. W thomson lord ke vin 18241907 este enunciado implica.
This implies that it is impossible to build a heat engine that has 100% thermal efficiency. Nov 06, 2012 cosmological perturbations are generally described by quantum fields on curved but classical spacetimes. Nadler department of applied mathematics, telaviv university, ramataviv, 69978 telaviv, israel. Second law of thermodynamics hyperphysics concepts. Measurement of plancks constant through black body radiation. Scribd is the worlds largest social reading and publishing site. Price university of arizona 7 may 2008 the experiment used a black body approach to experimentally measure plancks reduced constant, by using the planck radiation law, which relates the intensity.
