Understand why temperature is constant

In summary, the temperature of a system remains constant when the rate of heat entering the system is equal to the rate of heat leaving the system, known as thermal equilibrium. Factors such as the amount of heat added or removed, specific heat capacity, and insulation can affect this constancy. Temperature also plays a crucial role in the behavior of matter, affecting particle movement and potential phase changes. In a closed system, temperature can only remain constant or decrease due to the law of conservation of energy. Temperature is typically measured using a thermometer, with the most commonly used scales being Celsius, Fahrenheit, and Kelvin.

Does anybody knows the reasons why in Stratopause, Mesopause, Thermopause regions of the atmosphere the temperature is constant? Thanks in advance.

It is not.

Here are the temperature variations with altitude: http://vortex.plymouth.edu/atmosphere/layers.html

Beware that the temperature profile shown in that link is idealized one. It is not at any time, and space representative of real atmosphere. This may result only if years and years of data are averaged taken be the same instrument, or certain statistical methods applied. (just for clarity)
 

1. Why is temperature constant?

The temperature of a system remains constant when the rate of heat entering the system is equal to the rate of heat leaving the system. This is known as thermal equilibrium.

2. What factors affect the constancy of temperature?

The constancy of temperature can be affected by various factors such as the amount of heat added or removed from the system, the specific heat capacity of the material, and the insulation of the system.

3. How does temperature affect the behavior of matter?

Temperature plays a crucial role in the behavior of matter as it affects the speed at which particles move and interact with each other. As temperature increases, the particles move faster and the system may undergo phase changes such as melting or boiling.

4. Can temperature ever change in a closed system?

In a closed system, where there is no exchange of matter with the surroundings, the temperature can only remain constant or decrease due to the law of conservation of energy. It is not possible for the temperature to increase in a closed system without an external heat source.

5. How is temperature measured?

Temperature is typically measured using a thermometer, which is a device that uses the expansion or contraction of a material (such as mercury or alcohol) to indicate the temperature. The most commonly used temperature scales are Celsius, Fahrenheit, and Kelvin.
