The Thermosphere feels very cold to us because of its low Thermal Energy.There are very few particles in the Thermosphere, so even if they were very, very hot, it would feel cold.
The thermosphere has very low density of molecules, so even though it has high temperatures, there are very few molecules to transfer that heat to objects such as satellites. This is why satellites can operate in the thermosphere without overheating.
Diamond feels neither cold nor hot to the touch because it has high thermal conductivity, meaning it quickly adjusts to the temperature of your skin. This property makes it feel like it is at the same temperature as your skin.
The temperature difference between the object and your body's temperature determines how hot or cold something feels when you touch it. Heat transfer occurs from the object to your skin if it is hotter than your body temperature, making it feel warm. Conversely, if the object is colder than your body temperature, heat is transferred from your skin to the object, making it feel cold.
Humidity
The sense of temperature, known as thermoreception, allows you to feel hot and cold sensations. Specialized nerve endings in your skin detect changes in temperature and send signals to your brain to interpret these sensations.
The thermosphere has high temperature because the few molecules present can absorb high-energy solar radiation. However, since there are so few molecules, the heat energy is not readily transferred to a thermometer, so it would not feel hot to us.
Temperatures in the thermosphere can vary widely, ranging from about 500°C (932°F) during the day to 2000°C (3632°F) or more during periods of high solar activity. However, it is important to note that the thermosphere is not like a typical environment on Earth where we feel the temperature – the sparse density of gas molecules means that the "hot" thermosphere would not feel hot to our skin.
The thermosphere has high temperatures because it absorbs intense solar radiation due to its position in the atmosphere, causing the molecules to heat up. However, despite the high temperature, the thermosphere is not hot in the conventional sense as the density of the particles is very low, so a thermometer would not register the temperature as high as it feels.
It has a high temperature but it is not hot. Temperature (kinetic energy) and hot (thermal energy - a way of transferring energy between objects) are not the same thing. Temperature is the average velocity of particles, which in the thermosphere is quite high, but they are far less dense than in the troposphere, which means that they collide much less often and those fewer collision mean less energy transfer (less heat).
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
The thermosphere can reach temperatures as high as 2,500 degrees Celsius (4,532 degrees Fahrenheit) due to the absorption of high-energy solar radiation. However, despite these high temperatures, the thermosphere would not feel hot to us because the air density is so low that it cannot transfer much heat to objects passing through it.
A person would feel cold in the thermosphere because although the temperature is very high due to the sun's radiation, the air density is extremely low, so there are fewer air molecules to transfer heat to the body. The lack of air molecules means there is less heat conduction, making it feel cold to a person.
The thermosphere has the highest temperature of all the atmospheric layers due to the absorption of high-energy solar radiation by the sparse gas molecules present at that altitude. As these molecules absorb energy, their kinetic energy increases, leading to higher temperatures, which can exceed 2,500°C (4,500°F) or more. However, despite the high temperatures, the thermosphere would not feel hot to a human because the gas density is extremely low, meaning there are not enough molecules to transfer heat effectively.
The thermosphere, one of the outer layers of Earth's atmosphere, has high temperatures but does not feel hot to us because of the extremely low density of molecules in this layer. The lack of molecules means that there is not enough matter to transfer heat to our bodies, making it feel cold even though the temperatures are high.
The upper layer of the atmosphere is called the thermosphere because temperatures in this region can reach very high values, up to thousands of degrees Celsius. This is due to the absorption of solar radiation by gases in the thermosphere. Despite the high temperatures, the thermosphere would not feel hot to our skin because the air density is so low.
The thermosphere is an upper layer of the atmosphere where the heavier molecules (notably oxygen) are dense enough to absorb a significant part of the high-intensity radiation from the Sun. But this part of the atmosphere is still so thin than an object placed there would encounter very few of the high-energy (high temperature) molecules. Despite the air molecules present, the thermosphere is essentially a vacuum. The International Space Station orbits within the thermosphere, at an altitude of 280 to 460 kilometers (175 to 285 miles). The range of the thermosphere is from about 100 to 600 kilometers (60 to 360 miles) above the Earth's surface.
JT may possibly be hot because the temperature is high. When the temperature inside or outside is high, it can make the body feel very hot. At that point sweating will usually occur and cool it down.
