Why does the thermosphere have the highest temperature of all atmosphere layers?

Answer 1

about 90 millibars or about 100 millibars or bewteen it

Answer 2

Because there is no air, there will be no air pressure as well. So the pressure will be very near a perfect vacuum. Depending on where you are in space, there are very large thin gas clouds, stray bits of dust and a few atoms buzzing around. There may not be any parts of space that are absolutely pure vacuum. No air, no Earth - no air pressure.

Answer 3

The surface temperature of the Sun is about 12,000 degrees Kelvin; the core is believed to be about 15 million degrees K. Obviously, we've never actually MEASURED the temperature of the Sun's core, and we could be off a bit.

Answer 4

Yes. The atmospheric pressure in space is pretty close to "zero". You can measure, or calculate, the pressure in terms of "atoms per cubic meter".

Curiously, it is the "pressure of space" that may prove to be the limit as to how fast spacecraft can travel. When your speed increases, your spacecraft will run into, and push aside, more and more of those stray atoms in space each second. Since those atoms will have some tiny mass, and won't be moving all that fast, they will exert a retarding force very much like air resistance to an aircraft.

We do not yet have any data on the density of the interstellar gas in space.

Answer 5

How Exospheres temperature changes is you would be in outer space so there really is no temperature at all but if you wanted to specific it would probably decrase because there is no atmosphere or air presure does that answer your question?!?!?!?

..it increases and decreases at a drastic rate depending on the amount of solar radiation received. -animeforever3

Answer 6

The highest temperature in the thermosphere is about 3,000o F (1500o C). However, The air in the thermosphere is thin, so not many atoms can hit a thermometre, so it would have a very low reading. With nothing to shield it from the Sun's rays, the few atoms in the thermosphere get excited and move very fast.

Answer 7

It depends on what you mean by "outer space".

One commonly accepted definition is that outer space begins at the Karman line, 100 km above sea level. At this height atmospheric pressure is about 1 Pa (pressure at sea level is about 101 kPa).

Beyond that, scientists generally don't talk in terms of "pressure" but instead use mass density to describe how empty (or not) space is. The average mass density of the universe has been estimated at around 1 hydrogen atom per cubic meter.

The pressure in outer space is so low that many consider it as non-existant. It has a pressure of 1.322 × 10-11 Pa. Pressure may be detected from the molecule of air or water hitting you. Since there is very little air and hardly ever water hitting you in space, pressure is almost zero or negligible.

Answer 8

The temperature within the exosphere varies, depending on whether you are looking at the "day" side of the Earth, or the "night" side of the Earth. Because the atmospheric molecules are so disperse at this altitude, their energy is related to the amount of solar radiation that is received. During the day, the temperatures can reach thousands of degrees Celsius. During the night, the temperatures can reach close to absolute zero.

Answer 9

The temperture of the sun depends on the location in the sun you are considering.

• At the core the temperature is 7 million degrees C
  
• Moving away from the core the temperture falls to 2 million C
  
• In the convective zone, plasma bubbles carry heat to the surface, it is about 2 million C
  
• The surface of the sun, or photosphere, is a relatively cool 5,500 C
  
• In the sun's atmosphere it rises again to 2 million C
  

Answer 10

The temperature of the sun varies. In the center of the sun the temperature is around 13,600,000 Kº, while in the surface the temperature is around 5,800 Kº.
