Increase.
Entropy is a measure of disorder. Heat is a very low order form of energy. Friction produces heat energy and hence entropy tends to increase due to friction.
There is always an increase in the entropy of the universe.
If a source of heat energy starts radiating from a point and continues without stop the entropy around that point will never decrease. As sun is the endless heat energy radiating source and surrounding's of that is known as universe accepted by everybody. So this is the example for the statement ' the entropy of the universe can never decrease.'
Entropy always increases.It is sometimes stated that an increase in entropy means an increase in disorder - though that is not a very accurate description.
entropy in the universe
Entropy is a measure of disorder. Heat is a very low order form of energy. Friction produces heat energy and hence entropy tends to increase due to friction.

Disorder
There is always an increase in the entropy of the universe.
Entropy is the tendency of the universe to become more disorganized. Photosynthesis decreases entropy because it takes a larger number of reactants and converts them into a more organized form of energy, where there are less products than reactants. 6 H2O + 6 CO2 ---> C6H12O6 + 6 O2
Life can appear to go against the second law of thermodynamics, which states that entropy tends to increase over time in closed systems. However, living organisms do not defy this law; they simply maintain a temporary order within themselves by consuming energy from their surroundings and releasing heat to maintain equilibrium in their internal environment.
The entropy of the universe is increasing
Entropy is the scientific concept of disorder and randomness that has many broad applications across different branches of physics. While it is not a law itself, it is central to understanding the Second Law of Thermodynamics, as objects that are in thermodynamic equilibrium are at their highest state of entropy.
Some energy is converted to light or motion or something, but all heat dissipates into the billions of objects in the universe causing an increase in entropy (disorder of the universe). This is referred to as the heat death of the universe.
If a source of heat energy starts radiating from a point and continues without stop the entropy around that point will never decrease. As sun is the endless heat energy radiating source and surrounding's of that is known as universe accepted by everybody. So this is the example for the statement ' the entropy of the universe can never decrease.'
No, because the entropy of the surroundings must increase more than the decrease in the water->ice transition, thus the net change in the entropy of the universe is positive, consistent with the second law.
