Hotter and dimmer.
It's much smaller, but much denser.

Dschubba is a binary star system with two stars: a blue star and a white dwarf star. The blue star is the primary star and the white dwarf is the secondary star.
An older star that has become small is called a white dwarf. White dwarfs are the remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed to a very dense state. They are very hot and small compared to their original size as a main sequence star.
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
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.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
No a white dwarf is a small compact star.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
No. A white dwarf is the remnant of a low to medium mass star.
A white dwarf star's temperature can range from approximately 7000K to 19000K.
No, a typical white dwarf star is roughly the size of the Earth.
A white dwarf is much larger than a neutron star.
A white dwarf is the remnant of a low to medium mass star.
