Question

What violates the second law of thermodynamics?

Answer 1

1. One way of explaining the second law of thermodynamics is that it is impossible to transfer heat from a colder body to a warmer body without doing some work.
2. It is a fundamental law of nature and thus far there has been no experiment or observation that has been seen to violate the second law of thermodynamics.

Hence, there is no known phenomenon or process that has been seen to violate the second law of thermodynamics.
