Why is the exosphere so hot?

The exosphere is extremely hot due to its proximity to the Sun and the high energy of the few particles present at that altitude. Although it has very low density, the particles in the exosphere can reach temperatures exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit) because they absorb solar radiation and have high kinetic energy. This temperature measurement can be misleading, though, since there are so few particles that heat transfer is minimal, making it feel cold to a spacecraft or satellite passing through.


Is mesosphere hot or cold?

It is a relatively cold atmospheric layer, only slightlywarmer than the exosphere (the outer most layer of Earth's atmosphere).


Thermosphere and exosphere are the first to receive the suns rays so they are very what?

Thermosphere and and Exosphere are the first ones to receive the suns rays so they can reflect to the clouds and the sun could reflect into the water and points to where it is needed Comment: I think the answer is "hot".


What is the name of the uppermost layer of the atmospherewhy does it feel cold thereeven though the temperature can be very high?

The uppermost layer of the atmosphere is called the exosphere. It feels cold there because, despite high temperatures, the density of air is extremely low, resulting in very few air molecules to transfer heat. Therefore, the heat energy is not felt in the same way as at lower altitudes, where air density is higher and more efficient at conducting heat. This phenomenon leads to a perception of cold in the exosphere despite the presence of high-energy particles.

Why does exosphere feel cold there even though the temperature can be very high?

The exosphere can feel cold despite high temperatures because temperature measures the average kinetic energy of particles, not how much heat is present. In the exosphere, particles are so sparse that they rarely collide, meaning there is little thermal energy transfer to a human or spacecraft. Consequently, even though individual particles can move at high speeds, the overall sensation of heat is minimal due to the vast distances between them.


Is the temperature in the thermosphere and exosphere very cold?

yes

Which part of the atmosphere has the highest temperature?

If you are talking about Earth the Exosphere can reach temperatures of 2,500 °C (4,530 °F) during the day. Even though the temperature is so high, you would not feel warm even in the thermosphere which can get up-to 1,500 °C (2,730 °F), you would feel no heat due to the fact there are so few molecules and it is so close to vacuum. Since there is no clear boundary between outer space and the exosphere, the exosphere is sometimes considered a part of outer space. So people use the Thermosphere as the delineator

Why do you feel cold when you drink cold water?

Our body temperature is high then cold water so when it comes in contact with our body energy in the form of heat is transferred from body to water so it decreases our body temperature and we feel cold.


Why you always feel cold even the weather is not so cold?

Because you re sick.


What does elephant do for a cold?

Nothing. As he is Fat and his metabolic rate is fast. So he does not feel cold.

Is exosphere part of the climate system?

Yes, the exosphere is the outermost layer of Earth's atmosphere and is not typically considered part of the climate system. The exosphere is composed of very low-density gas particles and extends into space, where atmospheric interactions become less significant in influencing Earth's climate.
