Why are dwarf plants are hot but dim?
I assume you mean a DWARF STAR. There are different types of dwarf stars; the white dwarfs are fairly hot - but the reason they are dim is that they have a very small surface area.
Is a white dwarfs hot and dim or hot and bright?
As the name white dwarf implies, this is a small type of star, and it has less surface area from which to radiate light, so even if it is hot, and giving off lots of light per square mile, there are fewer square miles than in larger, non-dwarf stars, so there is less total light being emitted.
A star that is very hot but dim is a?
That might be a white dwarf.
A star that has expanded and cooled?
The general category is known as a dead star. There are three kinds of dead stars: 1. a white dwarf, which oddly enough by its description does not seem to be a dead star - "a dim very hot star" 2. a neutron star (viewed as a typical pulsar close to a normal star, but emitting x-rays); or 3. A black hole. The smallest and least dense stars become white dwarfs and the biggest, densest stars become black holes.
What are the characteristics of white stars?
It is the Post-Main sequence star that burns helium. They are considered giants, unlike our sun, which is a Yellow Dwarf. they are extremely hot and large.
What best describes stars?
hot,dim stars.
What best describes giant star?
hot, bright stars
Do stars that are very hot and very dim have a small mass or a small radius?
stars that are dim probably have both a small mass and a larger radius.
How white dwarf stars can be both hot and dim?
White Dwarf Stars are very hot, like a ball of fire. They are dim because they are small and very far away.
Red-hot and blue-hot stars appear white to the eye because?
they are too dim to fire the cones

Stars glow because?
Because they are extremely hot.
What stars are extremely luminous but not hot?
Red giants, red supergiants.
Are a stars outer layers hot?
Yes! Stars are made out of many gases that are extremely hot. But a sun can also have black spots on its surface which are cold.

What are stars really?
Stars are enormous balls of extremely hot gas, which are similar to our sun, but much farther away.
What types of stars are dim and hot?
There could be many answers as dim and hot are mutually exclusiveBrightness (or dimness for that matter) is defined as a stars luminosity and it's distance from the observer.So a hot star could be very far away and appear dim, whereas if it was relatively close, it would appear bright.A hot but small star, would appear dim at a close distance.However, in all likelihood the answer you might be looking for is either:Neutron Star - Very small and very hotWhite Dwarf - Small and very hot
