What is the property of matter where it changes volume when it changes temperature?

Answer 1

The property of solids in which they enlarge when warmed is thermal expansion. The opposite, shrinking when cooled, is thermal contraction. This property greatly effects how bridges, sidewalks, and concrete roads are made. They all have "expansion gaps," gaps between sections that allow the sections to expand in the heat of summer. Without those, the concrete would break and the bridges would warp and bend.

Answer 2

The property of matter that relates to changing volume when changing temperature is thermal expansion. As temperature increases, the particles within a material gain kinetic energy and move further apart, causing the material to expand or increase in volume. Conversely, as temperature decreases, the particles lose kinetic energy and move closer together, leading to contraction or a decrease in volume.
