Question

According to second law of thermodynamics, the entropy of the
universe
(a) decreases
(b) increase
(c) remains same
(d) none of these​

Answer 1

Answer:

There is yet another way of expressing the second law of thermodynamics. This version relates to a concept called entropy. By examining it, we shall see that the directions associated with the second law—heat transfer from hot to cold, for example—are related to the tendency in nature for systems to become disordered and for less energy to be available for use as work. The entropy of a system can in fact be shown to be a measure of its disorder and of the unavailability of energy to do work.
