When an object gets hotter, the particles within the object gain more energy and start to move faster. This increased movement causes the particles to spread apart, leading to expansion of the object. If the object is a solid, the increased energy may be enough to break the bonds holding the particles together, causing the object to melt and change state.
Thermal expansion is when something gets bigger (expands) as it gets hotter and smaller (contracts) as it gets colder. This happens because the particles inside the object move faster and spread out when heated, causing the object to expand. This phenomenon is why bridges have gaps and train tracks have small spaces between the rails.
If the size of an object gets bigger, the speed of the particles within it generally decreases. This is because the larger size allows for more interactions and collisions between the particles, which can lead to a decrease in overall kinetic energy and thus a decrease in speed.
When the density of a fluid gets hotter, it usually decreases. This is because as the fluid gets hotter, its molecules gain energy and move farther apart, causing the fluid to expand. This expansion leads to a decrease in density.
Typically, faster movement of an object is associated with higher temperature. This is because temperature is a measure of the average kinetic energy of particles in an object, and faster movement indicates higher kinetic energy, leading to higher temperature.
When a wet object gets dry, the water molecules on the surface of the object evaporate into the air, reducing its moisture content. This process is driven by temperature, airflow, and humidity levels in the surrounding environment.
The particles move faster. Thermal energy is a measure of kinetic energy of molecules.
The air will cool down, while the other object gets hotter.

Its clocks run faster.It gets hit with more cosmic and solar radiation.It gets hotter and colder more easily.It gets lonely and scared in the dark.
It gets hotter
Its particles gain energy and move faster. (See Kinetic Theory.) Eventually, they can change state (or burn, in some cases.
It gets hotter
When the material gets closer to the core it gets hotter and more dense.

density changes when something is heated or cooled because the tiny particles inside the object are either separating(with heat) or getting closer together(cold)
