Answer:

Liquids tend to expand and contract based on heat differences

Explanation:

In a liquid solid or, there is a dynamic balance between the cohesive forces that hold the atoms or molecules together and the conditions created by temperature; Higher temperatures imply greater distance between atoms.

Thermal expansion occurs when an object expands and becomes larger due to a change in the temperature of the object.
