Electrical cables that are strung from pole to pole are made of metal (usually aluminum or copper, in the U.S.). In hot weather, the cables get longer, which causes them to sag lower than they do in the winter. When the distance between poles is long, it can be pretty obvious.
Example sentence - Our homework assignment is to give an example of thermal expansion and explain why it happens.
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
A common difficulty caused by thermal expansion is the warping or cracking of materials such as metal or concrete when they are exposed to extreme temperature changes. For example, railroad tracks can buckle in hot weather due to thermal expansion if proper allowances are not made.
The expansion of matter upon heating is an example of a thermal expansion, which is the tendency of matter to change in volume, area, and length in response to a change in temperature.
Some non-examples of thermal expansion would include the boiling of water, which involves a phase change rather than expansion due to temperature increase, and the stretching of a rubber band, which is a different mechanism of deformation unrelated to temperature change. Additionally, the growth of a plant is not an example of thermal expansion.

This is an example of thermal expansion, where the liquid in the thermometer expands as it is heated, causing it to rise within the tube.

Well, friend, one beautiful example of thermal expansion being used for good stewardship is in the design of bridges. Engineers use the principles of thermal expansion to ensure that bridges have room to expand and contract with temperature changes, preventing damage and ensuring their longevity. It's a wonderful harmony between nature's laws and human ingenuity, creating structures that can stand the test of time while respecting the environment.
The function of an expansion valve is to regulate the flow of a substance. One example is a thermal expansion valve which regulates the flow of cooling substances within a device.
