“Understanding Expansion: Definition, Characteristics, and Examples”

GridKids.id – Expansion is the phenomenon of changing or increasing the dimensions or volume of an object caused by an increase in the heat temperature of the object.

Expansion can occur in several substances such as solids, liquids and gases.

Every object that expands differs from one another depending on the temperature, the coefficient of long expansion or the expansion power of the object.

The effect of this expansion is often used for the development of various types of technology.

So what are the characteristics of expansion?

The characteristics of expansion are physical changes in shape and structure.

Changes occur because they are heated and experience changes in area. An object that experiences expansion generally comes from a class of objects that expand easily when exposed to hot temperatures.

Objects that experience expansion are iron, sheets of glass, mercury, and others. Meanwhile, there are also objects that are difficult to expand because their expansion capacity is low and lacking, so it is difficult to see the results of expansion in these objects.
