No, a red giant is not an old, very dense hot star that is cooling. Instead, it is a late stage in the evolution of a star that has exhausted the hydrogen in its core and is now fusing helium or heavier elements. As a result, the outer layers expand and cool, giving the star its characteristic reddish color. While red giants can be quite large, they are not notably dense compared to other stellar types, like white dwarfs.

What is an old very dense hot star that is cooling called?
An old, very dense, hot star that is cooling is called a white dwarf. These stars are the remnants of medium-sized stars that have exhausted their nuclear fuel and shed their outer layers. Over time, they gradually cool and fade, eventually becoming faint stellar remnants known as black dwarfs, though the universe is not old enough for any black dwarfs to exist yet. White dwarfs are primarily composed of electron-degenerate matter, which accounts for their high density.
How can a star that has more mass than the sun be smaller than your sun?
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
What is an expanding star after exhausting its hydrogen fuel called?
An expanding star after exhausting its hydrogen fuel is called a red giant. This stage occurs when the core contracts and heats up, causing the outer layers of the star to expand and cool, giving it a red color.
Is a star's outer layer hot and dense?
Yes, a star's outer layer, called the photosphere, is hot and dense. This is where most of the visible light and heat emitted by the star originate. The temperature and density of the photosphere vary depending on the type and age of the star.

What are super-giant star?
super giants are a very very big star
What star is a red super giant?
Its a very large star that is coming to the end of its life. A star will expand as the forces change within, caused by changes in the fuel that it uses. they are very large and red, indicating a lower temperature. They are also not very dense, so sometimes their mass is relatively low compared with their size.
Is a red giant an old dense cool star?
A red giant [See related question] is the final part in a stars main sequence [See related question] life. It is old but not very dense nor cool but certainly cooler than when it was a main sequence star.
Do star grow bigger as they come older?
Most stars (including our own sun) as they grow older, eventually cool, expanding into a red-giant. After a period of time as a red-giant, they shrink to a hugely dense but very small white dwarf.
Is the biggest star in the world the red giant?
The answer to this question is yes. It can vary, but not very much. Yet, the red giant is the coolest star.
What is the last element to be formed in a very large star as it contracts from the red giant stage?
The last element to be formed in a very large star during its contraction from the red giant stage is iron. As the star's core becomes increasingly hot and dense, nuclear fusion processes create heavier elements up to iron. However, fusion of iron does not release energy, leading to a halt in the fusion process and eventually resulting in the star's collapse and supernova explosion.
