Best Answer

Most things do contract when they are colder because the molecules are less agitated. When the item is warmer, the molecules in that object are very agitated causing them to spread apart, making the item larger. That is why they have "expanding spacers" in concrete sidewalks, because in the summer the temperature is hotter causing the concrete to expand. When the temperature is cooler, the concrete contracts back to its original state.
