WebAccording to the Second Law of Thermodynamics, heat will always flow spontaneously from hot to cold, and never the other way around. A refrigerator causes heat to flow from cold to hot by inputting work, … WebNov 7, 2024 · In fact, whether a process is possible is governed by both the first and the second laws of thermodynamics. There are two classical statements of the second law of thermodynamics; one imposes the limits on the operation of heat engines, and the other on the operation of refrigerators and heat pumps.

Second Law of Thermodynamics - Georgia State University
WebThe Kelvin-Planck statement is the statement of the second law of thermodynamics for heat engines, while the Clausius statement is the statement of the refrigerators and heat pumps. These two statements are equivalent since it can be shown that if one statement is violated, the other one is also violated and vice versa [1] . http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/seclaw.html WebThe EER of an air conditioner or refrigerator can be expressed as EER = Q c / t 1 W / t 2, 15.45 where Q c is the amount of heat transfer from a cold environment in British thermal units, t 1 is time in hours, W is the work input in joules, and t 2 is time in seconds.
