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.
Generally, all metals contract when cooled. However, the rate at which they contract depends on their coefficient of thermal expansion. In general, materials with higher coefficients of thermal expansion will contract more when cooled.

Oil does expand when heated and contracts when cooled.
When liquids are cooled, their molecules slow down and move closer together, which causes them to contract or solidify, depending on the substance. This process is known as freezing or solidification. The specific behavior of a liquid when cooled will depend on its chemical composition and temperature.
Superconducting materials.
Generally, all metals contract when cooled. However, the rate at which they contract depends on their coefficient of thermal expansion. In general, materials with higher coefficients of thermal expansion will contract more when cooled.
Most materials contract and become denser as they are cooled due to the decrease in thermal energy causing the atoms or molecules to move slower and come closer together. However, certain materials such as water expand when cooled to form ice, which is less dense than liquid water.

When materials are heated, the particles gain kinetic energy and move faster, leading to expansion of the material. Conversely, when materials are cooled, the particles lose kinetic energy and move slower, causing the material to contract or condense.
Materials that expand and contract in response to changes in temperature are typically referred to as thermal expansion materials. These materials expand when heated and contract when cooled, which can be useful in various applications such as in thermostats, bimetallic strips, and expansion joints.
Yes, lead does expand when heated and contract when cooled, just like most materials. This property is known as thermal expansion and contraction.
No
Yes, solid materials expand when heated and contract when cooled. This is because heating causes the atoms and molecules in the material to vibrate more and increase their kinetic energy, leading to expansion. Conversely, cooling decreases their kinetic energy, causing them to move closer together and contract.
No, gasses expand when heated and contract when cooled.
Liquids expand when heated and contract when cooled.
No, metals always expand when heated and contract only when cooled.
yes they do
