RE: Refrigerators and Air Conditioners: The cool guys of Thermodynamics
Nice little post but it's wrong to say that Refrigerators and Air Conditioners break the second law of thermodynamics. According to the second law of thermodynamics, the heat never flows from a cold body to a hot body spontaneously. Refrigerators and Air Conditioners do transfer heat from a lower temperature to higher temperature but they require external work. The entropy change is also positive in these machines, so they don't violate the second law :)
Thanks for the contribution.
I expounded on that within the post. Since the second law of Thermodynamics asserts that heat never flows from lower temperature to higher temperature and there are devices that can do that, it may look to a common man that those devices are breaking the law.
But i explained why what one may think at first isn't really the case and how, in fact, refrigerators and air conditioners obey the second law to function.
Thanks for stopping by. I appreciate.
