When a substance freezes, its thermal energy decreases. This is because the molecules within the substance slow down and move closer together as they form a solid structure.
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
The increase in volume of a substance due to an increase in temperature is called thermal expansion. This occurs because as the temperature of a substance rises, the particles within it gain energy and move more, causing them to spread out and increase in volume.
Heat increases thermal energy by transferring energy to a system, causing the particles in the system to move faster and increase their kinetic energy, which in turn raises the system's overall thermal energy.
Temperature is a measure of the average kinetic energy of particles in a substance; it does not directly indicate the total amount of thermal energy. Thermal energy is the total kinetic and potential energy of particles in a substance. While an increase in temperature generally corresponds to an increase in thermal energy, it is not a direct measure of the total thermal energy in a substance.
The temperature of the substance will decrease. Scientists refer to the entire process and its effects as "cooling". But my dick is hotter. >:)
How does an increase in the total energy of the particles in a substance affect the thermal energy of the substance.

thermal expansion
An increase in size of a substance in response to an increase in temperature is known as thermal expansion. This occurs because as temperature rises, the particles in the substance gain more energy and move faster, causing the substance to expand. Thermal expansion is a common phenomenon observed in solids, liquids, and gases.
The temperature of the substance will increase when thermal energy is added without changing state. This is because the thermal energy is causing the particles within the substance to move faster, resulting in an increase in temperature.

Thermal Decomposition
Thermal energy at the molecular level is a reflection of how fast their random motion and how "agitated" they might appear were you able to view them. In more detailed terms their nett thermal energy U is the sum of U(rot), how fast they are spinning, + U(trans) - how fast they are moving in one particular direction, and + U(vib) - where the atoms in the molecule would seem to bounce back and forth in their bonds with respect to the position of other atoms. Increasing the thermal energy would increase the speed of these motions.
