Supergiants have relatively low temperatures compared to smaller stars like the Sun. Their surface temperatures typically range from 3,500 to 5,000 K. Despite their enormous size, they appear red or orange.
What else can I help you with?
What type of stars have a very low temperature and a very high absolute magnitudes?
The red giants are very bright and have a relatively low temperature, but they are still red hot, that's why they glow red and not white. Have a look at Betelgeuse or Aldebaran in binoculars, or Antares if you get a chance in the summer, and compare them with a white star like Rigel or Vega.
What is the surface temperature of the star Sadalsuud?
Sadalsuud, also known as Beta Aquarii, has a surface temperature of approximately 6,000 to 6,500 Kelvin. This places it in the category of a spectral type G star, similar to our Sun. Its relatively high temperature contributes to its brightness and distinct yellowish hue in the night sky.
Of what substance are the inner planets mostly composed of?
The inner planets, including Mercury, Venus, Earth, and Mars, are composed mostly of rock and metal. They have solid surfaces and relatively high densities compared to the outer gas giants.
Why does a cool distant supergiant star such as betelgeuse have a high luminosity?
Betelgeuse, a cool distant supergiant star, has a high luminosity primarily due to its large size and surface area. Despite its relatively low temperature, its vast volume allows it to emit a significant amount of energy. The combination of its expansive radius and the Stefan-Boltzmann Law, which states that a star's luminosity increases with the fourth power of its temperature, results in Betelgeuse's impressive brightness. Thus, even with a lower temperature, its sheer size compensates, leading to high luminosity.
What type of stars have high absolute magnitude but low temperatures?
Red giants.

Is hot a preposition?
No, it is not. It is an adjective meaning a relatively high but unspecified temperature.
Which element at room temperature is a poor conductor of electricity and has a relatively high electronegativity?
Sulfur has relatively high electronegativity and is also a poor conductor of electricity at room temperature. Fluorine has the highest electronegativity and copper is a good conductor of electricity.
What is the definition of the phrase super hot?
There is no dictionary definition of "super hot". However, the definition of super is very good or pleasant and the definition of hot is having a high degree of heat or a high temperature.
What type of stars have a very low temperature and a very high absolute magnitudes?
The red giants are very bright and have a relatively low temperature, but they are still red hot, that's why they glow red and not white. Have a look at Betelgeuse or Aldebaran in binoculars, or Antares if you get a chance in the summer, and compare them with a white star like Rigel or Vega.
What are the factors affecting the pressure?
Type of molecule: intermolecular forces between molecules are: * relatively strong, the vapor pressure will be relatively low. * relatively weak, the vapor pressure will be relatively high. Temperature: * higher temperature, more molecules have enough energy to escape from the liquid or solid. * lower temperature, fewer molecules have sufficient energy to escape from the liquid or solid.
Is hot a conjunction?
No, it is not. The word hot is an adjective for relatively high (but unspecified) temperature. It can also (arguably) be an adverb.
Does metallic have a high melting point?
Not all of them. Mercury is liquid at room temperature. Bismuth and lead melt at relatively low temperatures.
What quarterback had a ridiculously high 88 percent completion percentage in a Super Bowl game?
Phil Simms of the New York Giants in Super Bowl XXI (22 completions in 25 pass attempts).
