Answer:
It expands to its secluded area.
Step-by-step explanation:
Any substance that is heated will have its molecules and atoms move more quickly, expanding the distance between them all. The term "expansion" is used more frequently to describe this growth in space. Heat causes all stuff, including solids, liquids, and gases, to expand.
In some cases, heating solids causes them to transform into liquids. However, they could revert to their solid state after cooling. Similar to this, certain liquids turn into gaseous states when heated. Instead of altering their condition, gases, on the other hand, frequently expand and raise the pressure inside a container.
Scientists typically blow up balloons to test the expansion of gases, exposing some to the light while leaving others at room temperature. It is demonstrated that heat causes gases to expand when balloons exposed to the sun grow in size while those at ambient temperature remain unchanged.
