Does Rigel have a higher luminosity and a lower surface temperature than the sun?
Yes, Rigel has a much higher luminosity than the Sun, being around 120,000 times more luminous. However, it also has a lower surface temperature than the Sun, with a surface temperature of around 11,000 Kelvin compared to the Sun's temperature of approximately 5,500 Kelvin.
Which star has a higher luminosity and a lower surface temperature than the sun Rigel Bernard's star Alpha Centauri or Aldebaran?
Aldebaran has a higher luminosity and a lower surface temperature than the Sun. Rigel has a higher luminosity but a higher surface temperature than the Sun. Bernard's Star and Alpha Centauri have lower luminosity and higher surface temperatures compared to the Sun.
What star is brighter Betelgeuse or Rigel?
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.
What type of star has a high temperature and low luminosity in the HR diagram?
A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
How does altitude relate to temperature?
The higher the altitude the lower the temperature.

What luminosity of a star is related to its?
The luminosity of a star is related to its surface temperature and size. Hotter stars with larger surface areas tend to have higher luminosities, while cooler stars with smaller surface areas have lower luminosities.
How does luminosity affect the CHZ?
Luminosity affects the habitable zone (CHZ) by determining the distance at which a planet would need to be from a star to have the right temperature for liquid water to exist on its surface. Stars with higher luminosity would have habitable zones farther out, while stars with lower luminosity would have habitable zones closer in. This means that the size and location of the CHZ around a star depend on its luminosity.

A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
Is energy as heat flow from a lower temperature to a higher temperature true?
No, energy does not naturally flow as heat from a lower temperature to a higher temperature. Heat energy always flows from a higher temperature to a lower temperature in accordance with the second law of thermodynamics.
What is the name for thermal energy that is transferred from a higher temperature to a lower temperature?
Thermal energy always flows from higher temperature to lower temperature. This is the nature of heat.
Is the altitude higher or lower if the temperature remains the same?
lower
How does altitude relate to temperature?
The higher the altitude the lower the temperature.
Are the temperature of the moon are higher or lower than the earth?
the temperature of the earth is lower than the Earth.
Does solid dissolves more quickly in wter of higher temperature than lower temperature?
Solids dissolve in water of a higher or lower temperature depending on what the solid actually is.
