Question

The concept that events in the universe have direction and that they tend to proceed from a state of higher energy to a state of lower energy is known as _________. As a result, in any energy transformation, there is a decreasing availability of energy for doing additional work.

Answer 1

Answer: Second law of thermodynamics

Step-by-step explanation:

The second law of thermodynamics states that the net entropy of an isolated system cannot decrease over a period of time.

The increase in entropy means irreversibly is associated with a natural process and entropy of the universe is always increasing.

Entropy is a sum of system and surrounding thus entropy associated with the irreversible process does not necessarily mean positive entropy(surrounding entropy might be decreasing).
