Why is it necessary to use special instruments to measure the temperature of the atmosphere in the thermosphere layer?
The thermosphere is the last layer of the atmosphere. Special instruments are needed to measure its temperature because there are very few particles in the thermosphere that would strike a conventional thermometer to heat it.
What happens to temperature in the thermosphere when altitude increases?
In the thermosphere, temperature increases with altitude due to the absorption of high-energy solar radiation by the sparse gas molecules present at that height. Despite this temperature increase, the thermosphere may feel very cold to us as the low density of molecules means that there is not enough matter to transfer heat efficiently.
How does the temperature change with altitude in the thermosphere?
In the thermosphere, the temperature increases with altitude due to the absorption of high-energy solar radiation by the few particles present in this layer. Despite the high temperatures in the thermosphere, the low density of particles means that the air would feel extremely cold to the touch.
Why does the temperature in the thermosphere steadily rise?
The temperature in the thermosphere rises because of the absorption of high-energy solar radiation by gases like oxygen and nitrogen in this layer of the atmosphere. The density of these gases is extremely low, so there are few particles to absorb the heat from the radiation, causing the temperature to increase significantly.
What is the density of the thermosphere?
The density of the thermosphere is extremely low, with only a few particles per cubic centimeter. This is because the thermosphere is the outermost layer of Earth's atmosphere, where gases are highly dispersed due to the low pressure at such high altitudes.
Why would a thermometer show a low temperature in the thermosphere?
A thermometer may show a low temperature in the thermosphere because the density of particles is so low that it cannot effectively transfer heat to the thermometer. The thermosphere is highly influenced by solar activity, leading to high temperatures despite the low density of particles.
Why would and ordinary thermometer show a low temprature in the thermosphere?
An ordinary thermometer would show a low temperature in the thermosphere because the thermosphere is characterized by very low air density and high energy particles. Regular thermometers rely on air molecules to transfer heat, but in the thermosphere, the low density of air molecules means that the thermometer cannot accurately measure the temperature of the sparse particles present.
What causes a thermometer to show a low temperature?
A thermometer may show a low temperature if it is exposed to a cold environment or if there is a decrease in the surrounding temperature that it is measuring. It could also show a low reading if the thermometer is placed incorrectly or is malfunctioning.
Why would an ordinary thermometer show a low temperature in the thermosphere?
Individual molecules of gas might be very hot, but there are too few of them to affect a thermometer much. Then the energy lost through black body radiation is more than the energy gained from the few molecules around it, making the thermometer temperature decrease until the lower equilibrium temperature is reached.
Why the thermosphere has a very high temperature?
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.
What is a Low-temperature thermometer?
what is the name of a thermometer which can measure low temperatures
Why is the temperature in the thermosphere not measured with a thermometer?
If a thermometer were placed in the thermosphere, it would register far below 0 degrees C! This may seem strange since the thermospher is so hot.(see answer to "what is one characteristic of each layer of the earth") How can this be explained? Temperatureis a measurement of how fast particles in the air move. The faster the air particles move the higher the temperature. And the particles present in the thermosphere are moving very fast. THerefore the particles themselves are very hot. But these particles are vry few and very far apart. There are not enough of them present to bombard a thermometer and warm it. So the thermometer would re3cord a temperature far below 0 degrees C.

What is Low sensitivity of a thermometer?
Low sensitivity of a thermometer means that the thermometer is not able to detect small changes in temperature accurately. This can result in less precise temperature readings and a reduced ability to differentiate between slight temperature variations.
What does it mean when a thermometer says L?
When a thermometer displays "L", it typically indicates that the temperature reading is below the thermometer's lower limit or range of measurement. This could be due to the temperature being too low for the thermometer to accurately detect.
What is the temperature of thermosphere?
The thermosphere can reach temperatures from 500 to 2000 degrees C or higher. But there is so little matter that the total heat content is extremely low.
Why does a Fahrenheit thermometer start where it does?
becausde the temperature doesn't usually get that low
