The Universe is expanding, so its size is increasing.
The total amount of entropy in the universe will always increase according to the second law of thermodynamics, which states that the entropy of an isolated system will tend to increase over time. This means that the overall disorder in the universe will continue to grow as processes occur and energy is dispersed.
It is space that is expanding. The amount of matter doesn't necessarily increase. This means that the average density of the Universe is decreasing.It is space that is expanding.

Yes, the entropy of the universe increases when a system undergoes a reversible process.
No, mass does not increase as the universe expands. Mass is a conserved quantity, meaning it remains constant in a closed system. However, the total amount of mass within an expanding universe stays the same, even though the volume of space it occupies increases.
Carbon density in the universe does not change over time as the total amount of carbon remains constant. The distribution of carbon throughout the universe may change due to elements being recycled through stellar processes, but the overall density of carbon remains relatively stable.
From an infinitesimally small point to the present size, the universe is still expanding as a result of the big bang.
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.
The entropy of the universe is increasing
The observable universe is constantly expanding due to the ongoing expansion of the universe. This means that the size of the observable universe is not constant and will continue to increase over time.
The entropy of the universe increases for spontaneous processes because the second law of thermodynamics states that in any spontaneous process, the overall entropy of a closed system will always increase over time. This is because the natural tendency of systems is to move towards a state of higher disorder and randomness, leading to an increase in entropy.
Whenever energy is transformed, there is always an increase in the total entropy or disorder of the system and its surroundings, in accordance with the second law of thermodynamics.
If Hubble's constant were to increase, it would mean that the rate at which the universe is expanding is also increasing. This could have implications for the age and size of the universe, as well as the eventual fate of the cosmos. Additionally, it could potentially impact our understanding of dark energy and the overall structure of the universe.
