Refrigerator 11 thermodynamic cgraph
According to the second law of thermodynamics, heat cannot spontaneously flow from a colder location to a hotter area; work is required to achieve this. An air conditioner requires work to cool a living space, moving heat from the interior being cooled (the heat source) to the outdoors (the heat sink). Similarly, a refrigerator moves heat from inside the cold icebox (the heat source) to the … WebQuestion 1. 300 seconds. Q.

WebFeb 20, 2011 · This is a refrigerator. So some work has to be done in order to do this. And whatever object that is doing the work-- it may be some, in the case of your refrigerator, it's a compressor. That is adding more entropy to the universe than the entropy that's being destroyed by our refrigerator. So this does not defy the second law of thermodynamics. WebThe Carnot engine cycle when acting as a heat engine consists of the following steps: Reversible isothermal expansion of the gas at the “hot” temperature. Isentropic (reversible adiabatic) expansion of the gas. Reversible isothermal compression of the gas at the “cold” temperature. Isentropic compression of the gas.
