When an object expands, the particles within the object move farther apart from each other, increasing the object's volume. When the object contracts, the particles move closer together, decreasing its volume. This expansion and contraction occur due to changes in temperature, pressure, or other external factors.
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.
In general, when an object expands, its volume increases. This occurs because expansion involves the individual particles within the object moving further apart from each other, leading to an overall increase in the amount of space the object occupies.
As an object contracts, its volume decreases while its mass remains constant. This results in an increase in the density of the object since density is defined as mass divided by volume.
The three factors are the: material properties (coefficient of thermal expansion), temperature change, and original dimensions of the object.
When heat energy causes an object to expand, its particles receive additional kinetic energy, causing them to move more rapidly and increase the space between them. This results in the object occupying a larger volume while maintaining its original mass.

the metal particles(talking about metals) near the hole will expand towards the hole making the hole smaller, and the particles at the extreme expands outwards..
A thermometer measures temperature by using a material that expands or contracts with changes in temperature. This material is usually mercury or alcohol. As the temperature of the object being measured changes, the material in the thermometer expands or contracts, causing the level to rise or fall on a scale, indicating the temperature.
The density decreases.

The temperature of an object affects its thermal expansion by causing its particles to move faster and spread out, leading to an increase in volume. Conversely, when the temperature decreases, the particles move slower and the object contracts.
