SUMMARY

An object's thermal energy decreases as its temperature drops, as demonstrated by the relationship between particle movement and temperature. When an object radiates more energy than it absorbs, its temperature decreases, leading to a reduction in the vibrational motion of its particles. This principle is fundamental to understanding thermal energy dynamics, particularly in systems approaching absolute zero, where particle motion ceases entirely. The discussion highlights the connection between temperature changes and thermal energy loss, which is also a key concept in superconductivity.

Homework Statement



I know that if an object radiates more energy than it absorbs its temperature will decrease, but what I'm trying to see is whether or not its thermal energy also decreases (I'm thinking yes, but not 100% sure).

Homework Equations





The Attempt at a Solution


 
Physics news on Phys.org
Thermal energy is the movement of particles within a solid / liquid / gas.

If the temperature of an object decreases, the 'vibration' of the particles within that object also slows down - the closer to absolute zero you get the slower the particles move, until the point you reach absolute zero when all motion stops.

So the system loses thermal energy when its temperature decreases and gains thermal energy when its temperature increases.

This is the basic principle behind super conductors.
