Webb10 apr. 2024 · Rubber is a polymer chain which breaks on heating leading to decrease in intermolecular distance. Hence, it contracts. Water at ordinary temperatures contracts and increases in density as it is cooled. But at about 4 ∘ C, it reaches a maximum density and then decreases in density as it approaches the freezing point. low income energy assistance program in texasWebb12 apr. 2024 · A crucial material comprising a pneumatic tire is rubber.
