Discuss the second law of thermodynamics and it... - SS1 Physics Heat and Thermodynamics II Question

The second law of thermodynamics deals with the direction of natural processes and the concept of entropy. It states that in an isolated system, the total entropy of the system and its surroundings always increases or remains constant. Entropy is a measure of the disorder or randomness in a system. The second law implies that spontaneous processes tend to increase the overall disorder or entropy of the universe. It also provides a criterion for the direction of heat transfer, stating that heat flows spontaneously from regions of higher temperature to regions of lower temperature.
