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.
They freezee
Oil does expand when heated and contracts when cooled.
Superconducting materials.
No. When water is cooled it contracts up to 4 degrees Celsius and then it begins to expand till 0 degrees Celsius. This is called the anomalous expansion of water.
contraction is is the decreasing of size in solids when cooled
Contract.
No
ummm it will definetely expand....if the materials you"re talking about is the term for science.
No, gasses expand when heated and contract when cooled.
Liquids expand when heated and contract when cooled.
The particles will contract.
No, metals always expand when heated and contract only when cooled.
yes they do
Metals, like most solids will contract when cooled. When cooled the atoms or molecules slow down, vibrating less often, causing a smaller average separation between them.
is it when thet get smaller
