Generally substances contract when cooled
Websubstances move faster when the substances are heated, and that solids expand when they are heated and contract when they are cooled. What about liquids? Do you think that they expand and contract the way solids do?

For this reason, bridges are built with metal expansion joints, so that they can expand and contract without causing faults in the overall structure of the bridge.
WebInsulators. Internal movement of molecules of a substance. Thermal energy. Transfer of thermal energy through solids by direct contact. Conduction. Process that transfers … WebA common observation seen in the behaviour of the substances is that they expand when heated as the density decreases and vice versa when the material is cooled. This is how substances generally react to heat. Let us now look at how water behaves when heated. The general tendency of cold water remains unchanged until 4 o C.
WebApr 27, 2024 · When you heat ice, the molecules gain kinetic energy, and the ice expands until it melts. But once all the ice has turned to water and the temperature starts rising again, expansion stops. Between 32 and 40 degrees Fahrenheit (0 and 4 degrees Celsius), the melted water actually contracts as the temperature rises.
