How hot are stars compared to the sun?
The hottest stars have surface temperatures of 50,000 Kelvin degrees. The Sun surface is only 5800 Kelvin degrees, which means that there are hotter starts than the Sun.
Is a star surface temperature related to its size?
The amount of power that a star produces in light is related to the temperature of its surface and the area of the star. The hotter a surface is, the more light it produces. The bigger a star is, the more surface it has.
How hot is the surface of the hottest star?
The hottest one measures ~210,000 K; the hottest known star. The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
Are stars much hotter than the sun?
The Sun is a star – and the stars of the night sky are Suns a bit like our own. Some stars are much bigger than our Sun (and weigh a lot more too), and are even hotter inside. In some cases it's hundreds of millions of degrees inside the star!
What is hotter than the Sun?
And the answer: lightning. According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees. Meanwhile, magma can reach temperatures near 2,100 degrees.
How hot is surface of sun?
5,778 KSun / Surface temperature
How hot is the surface of the Sun?
5,778 KSun / Surface temperature
How much more energy flux does a star that is 2 times hotter than the Sun output?
How much more energy flux does a star that is 2 times hotter than the Sun output? (The total energy given off depends on the fourth power of the temperature (Stefan-Boltzmann Law). If the temperature is 2x higher the energy output is 2x2x2x2=16x higher.)
How hot is the average star?
Generally, a star of our Sun's size will fuse hydrogen for around 8 to 10 billion years, putting out light and heat. An average star's surface temperature can range between 4,760 (2,900 Kelvin) and 12,140 (7,000 Kelvin) degrees Fahrenheit, hot!
Why are bigger stars hotter?
It's a positive feedback between gravitational heating and nuclear fusion that makes massive stars burn much faster and hotter than less massive ones — and thus massive stars exhaust themselves faster even with their greater mass. Massive stars, under the stress of tremendous gravity, live fast and die young.
What is hotter than the surface of the Sun?
According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees. Meanwhile, magma can reach temperatures near 2,100 degrees.
Is lava hotter than the Sun?
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
Is lava hotter than fire?
While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.
Is the Sun surface hotter than core?
The temperature of the Sun And just like walking away from a campfire, the temperature gets cooler further away from the core. The temperature of the Sun's surface is about 6,000℃, which means it's much cooler than the core. Also, it continues to cool down for a short distance above the surface.
How much more energy flux does a star that is 2 times hotter than the sun output recall the Stefan Boltzmann Law group of answer choices?
(The A star is 2x hotter so by the Stefan-Boltzmann Law is 2x2x2x2=16x brighter.
What is the heat flux at the surface of the sun?
Role of the atmosphere Solar flux just outside Earth's atmosphere is referred to as the “solar constant” and has a value of approximately 1373 W m− 2.
How hot is a yellow star?
The 5 Colors of Stars

How hot is a blue star?
between 10,000 K and 50,000 K The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.
Is the smaller the star the hotter it is?
Very massive stars, which can be over ten times the mass of the Sun, are the hottest and usually glow blue. Smaller stars, with less than half the mass of the Sun, are the coolest and usually glow red. The more massive, hotter blue stars do not "live" for as long as the smaller stars.
Do stars of the same temperature have the same spectral type?
Stars of similar size, temperature, composition and other properties have similar spectra and are classified into the same spectral class. The main spectral classes for stars range from O (the hottest) through B, A, F, G, K and M (coolest).
Would a diamond melt in lava?
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.
Is lightning hotter than lava?
Lightning is much hotter than lava. Lightning is 70,000 degrees Fahrenheit, compared to Lava at 2,240 degrees.
How hot is blue lava?
10,830 °F Truly-blue lava would require temperatures of at least 6,000 °C (10,830 °F), which is much higher than any lava can naturally achieve on the surface of the Earth.
How hot is blue fire?
Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood.
Is the corona of the Sun hotter than the surface?
The material in the corona is an extremely hot but very tenuous plasma. The temperature in the corona is more than a million degrees, surprisingly much hotter than the temperature at the Sun's surface which is around 5,500° C (9,940° F or 5,780 kelvins).
Are black holes hotter than the Sun?
Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.
How much more energy flux does a star that is 2 times hotter than the Sun output quizlet?
(The A star is 2x hotter so by the Stefan-Boltzmann Law is 2x2x2x2=16x brighter. Since it is hotter, Wien's Law tells us it emits energy at shorter wavelengths.)

Is there a purple star?
Although you can spot many colors of stars in the night sky, purple and green stars aren't seen because of the way humans perceive visible light. Stars are a multicolored bunch.
