Thermal expansion is used in thermostats, or heat-regulating devices.
Thermal expansion occurs when change in temperature causes change in object such as metal, which expands when temperature rises. Different metals have different expansion characteristics. A metal will change precisely with change in temperature. The rest is easy: apply techniques to switch circuits (furnace/AC) on and off with physical shape change of metal, calibrate switching to correspond to required temperature and measured temperature. This type of control is largely antiquated in thermostat control and replaced with PN junction linear change in base speading resistance used to control sophisticated energy saving equipment.
Expansion still used heavily in refrigeration control and heating protection and control.

thermostats contain bimetallic strips, which are strips of two different metals joined together. When the thermostat is on cool, thermal energy is released. when the thermostat is on high, thermal energy moves through the air (everywhere in the atmosphere).
My knowledge about thermal expansion borders on absolute zero.
Example sentence - Our homework assignment is to give an example of thermal expansion and explain why it happens.

Heat the metal lid (but try not to heat the glass jar as much) and the thermal expansion will make the lit easier to screw off (I do this often by running the lid under hot tap water).

Thermal Expansion. Each liquid or pure solid has a specific thermal of expansion. The thermal expansion of a substance is not linear, though for most of the temperatures we encounter in normal life, it is close enough to linear to be able to use a linear definition called the "Coefficient of Thermal Expansion".

Very low CTE - coefficient of thermal expansion.
For thermal expansion of the pipe, avoiding damage/clash to adjoining pipes.
To accommodate thermal expansion between reformer tubes and the outlet manifolding.
