What are the upper and lower limits for stellar surface temperature?
One way of classifying stars is by their temperature; stellar temperatures run from about 2500 Kelvin to about 50,000 Kelvin. Another way of classifying stars is by using the notorious OBAFGKM spectral classes.
Why is the maximum temperature of the 40 msun star less than the maximum temperature of the 20 msun star?
It will reach its maximum temperature during the Neutron Star stage of its life. This means that due to the different stages the two stars go through, the 20 Msun star will have a greater maximum temperature than the 40 Msun star.
What type of star has a high temperature and a high luminosity?
What type of star has a high temperature and a high luminosity? Blue Giants 19. What type of star has a low temperature but a high luminosity? Red Giants 20.
What star has a temperature of 6000K?
Colours and temperatures Others stars appear blue, such as Sirius, the Dog Star. Sirius has a surface temperature of around 15000K. Our Sun is an average yellow star, with a surface temperature of about 6000K.
What star has a high temperature and high luminosity?
What type of star has a high temperature and a high luminosity? Blue Giants 19.
Which star has the highest surface temperature quizlet?
Spica, with a spectral type of B1 (the closest to O in OBAFGKM), has the highest surface temperature.
What is the temperature of a star in Celsius?
The colour of a star indicates its surface temperature. The hottest stars glow blue-white with temperatures of 30,000-40,000° Celsius. White stars are about 10,000° C, while the coolest are the red stars with temperatures of around 3000° C.
What temperature are blue stars?
The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.
What is the highest temperature in Kelvin?
As such, it seems that the highest possible known temperature is 142 nonillion kelvins (1032 K.). This is the highest temperature that we know of according to the standard model of particle physics, which is the physics that underlies and governs our universe. Beyond this, physics starts to breakdown.
What type of star has a high temperature but a low luminosity?
White Dwarf What type of star has a high temperature but a low luminosity? White Dwarf 18.
Which stars have high luminosity and low temperatures?
red giant and supergiant stars (luminosity classes I through III) occupy the region above the main sequence. They have low surface temperatures and high luminosities which, according to the Stefan-Boltzmann law, means they also have large radii.
Which star has the highest surface temperature color?
The color of a star shows its surface temperature. Blue stars are the hottest, followed by white, yellow, orange, and red.
Which of the following stars has the highest temperature photosphere surface )?
The polarities of sunspot groups are the same in both hemispheres throughout the cycle. Which of the five stars has the highest temperature photosphere? Sirius B.
What temperature is a yellow star?
The temperature of a star defines the color it will give off. Above 6,000 Kelvin, and the star appears white. From 5,000 – 6,000 Kelvin, the star appears yellowish, and below 5,000 Kelvin, the star looks yellowish-orange.
Which color of the star has the highest temperature?
blue Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.
What is the maximum and minimum temperature?
MAXIMUM TEMPERATURE: The definition of maximum is the largest number or highest number of something that is permissible or possible. MINIMUM TEMPERATURE: The lowest temperature recorded—diurnally, monthly, seasonally, or annually, or the lowest temperature of the entire record.
What is the range of Kelvin scale?
Scientific definitions for Kelvin scale A scale of temperature beginning at absolute zero (-273.15°C or -459.67°F).
Which group of stars has high temperatures and high luminosity?
What type of star has a high temperature and a high luminosity? Blue Giants 19.
What has the highest surface temperature?
Two places hold the record for highest surface temperatures on the planet. Death Valley holds the record for the highest air temperature on the planet: On 10 July 1913, temperatures at the aptly named Furnace Creek area in the California desert reached a blistering 56.7°C (134.1°F).
Which star type has the highest temperature color?
The color of a star shows its surface temperature. Blue stars are the hottest, followed by white, yellow, orange, and red.
What color star has the lowest temperature?
The temperature of a star refers to its surface and that is what determines its color. The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body.
What is the highest possible temperature?
100 million million million million million degrees C Theoretically, the Planck Temperature (100 million million million million million degrees C) is the highest temperature that can be achieved, but the Hagedorn Temperature is even higher, at 2 x 1012 degrees. That's a lot of zeros.
What is temperature maximum?
Maximum temperature is the highest temperature at a place in a given time period . There is no limit for maximum temperature. It can go very high, upto an extent where it cannot be measured.
What is the upper fixed point of the Kelvin scale?
373K For the same reason, this scale of temperature is also known as absolute scale of temperature. On this scale, the lower fixed point i.e. the temperature of melting ice at normal pressure is +273K and the upper fixed point i.e. the temperature of boiling water at normal pressure is 373K.
Is 273 Kelvin hot or cold?
Water freezes at temperatures below 273 kelvins.
Which star has the lowest surface temperature?
Antares, with a spectral type of M1 (the furthest from O in OBAFGKM), has the lowest surface temperature.
