# Does temperature in static particles increase due to gravity?

• Felian
In summary, the conversation discusses whether particles in the Earth's core experience a temperature gain due to gravity and how this differs based on their distance from the core. It is mentioned that the net central force of gravity decreases but the pressure, density, and temperature increase as you move closer to the center depending on the material composition and equation of state. There is also a clarification that the topic involves gravity, density, and pressure rather than just gravity.

Hello, I was wondering if particles that have a set position such as for example particles within the Earth's core would experience a temperature gain due to gravity.
If kinetic energy is applied to the particles in the air due to gravity, then kinetic energy should also be applied to particles deep inside the Earth right? But because the particles don't really have anywhere to go I would expect this kinetic energy to be transformed into temperature.

If so, how do these gains in temperature differ based on distance to the core? The total force of gravity would be higher in the core because its average distance to other particles would be lower, but the forces do balance out completely at the exact core because it would come from all sides. How would these forces translate into thermal energy?

I think you are confusing gravity, density and pressure. The net central force of gravity decreases as you move closer to the center of the earth, but the pressure, density and temperature all increase. How exactly they do this depends on how far down you go, what the local material composition is, and what it's equation of state is.

## 1. Does the temperature of static particles increase with an increase in gravity?

Yes, the temperature of static particles does increase with an increase in gravity. This is due to the increased potential energy of the particles as they are pulled towards the center of gravity.

## 2. How does gravity affect the temperature of static particles?

The force of gravity causes static particles to move closer together, increasing their potential energy and therefore increasing their temperature.

## 3. Is there a direct relationship between gravity and the temperature of static particles?

Yes, there is a direct relationship between gravity and the temperature of static particles. An increase in gravity results in an increase in temperature, and a decrease in gravity results in a decrease in temperature.

## 4. Can the temperature of static particles be controlled by adjusting the force of gravity?

Yes, the temperature of static particles can be controlled by adjusting the force of gravity. By changing the strength of gravity, the potential energy and temperature of the particles can be altered.

## 5. Are there any other factors that can affect the temperature of static particles?

Yes, there are other factors that can affect the temperature of static particles, such as the material and composition of the particles, the surrounding environment, and external forces acting on the particles.
