Superconductivity is a purely quantum mechanical phenomenon. And as all quantum mechanical effects it disappears at high temperatures and/or large scale. One of ways to see quantum effects is to lower the temperature (in this case it's only way).
Generally speaking synthetic materials are man made and do not occur in nature. Example are plastics certain alloys etc. There are some things that can be both synthetic and natural such as some drugs and chemicals
energy movement from higher temperature regions
An earthquake can occur at any temperature, as it is caused by tectonic plates shifting beneath the Earth's surface, not by the temperature of the air or ground.
Because melting occur at high temperature; at this temperature bonds between particles are weaker.
Accidental explosions caused by electromagnetic radiation (EMR) can occur when the radiation interacts with flammable or explosive materials, such as gas, fuel, or certain chemicals. The energy from the EMR can spark ignition or cause a rapid increase in temperature, leading to an explosion. Proper handling and storage of flammable materials, as well as implementing safety measures around EMR sources, can help prevent such incidents.
The lowest temperature at which superconductivity can occur is called the critical temperature. This temperature varies depending on the material. Some superconductors have critical temperatures close to absolute zero (0 Kelvin), while others have critical temperatures as high as -140 degrees Celsius.
Scientists use absolute zero to study the behavior of materials at extremely low temperatures, as it is the lowest possible temperature that can be reached. This helps in exploring quantum phenomena, superconductivity, and superfluidity that occur at these temperatures. Additionally, absolute zero is used as a reference point for temperature scales such as Kelvin.
It was startling because it was said to be impossible by the BCS theory.
The discovery of high temperature superconductors was startling to scientists because it defied previous understanding of superconductivity, which was thought to only occur at very low temperatures. These new materials exhibited superconducting properties at relatively higher temperatures, opening up new possibilities for practical applications.
Changing the temperature or pressure of a material we can change the phase.
Iridescence occurs in certain materials because of the way light interacts with their surface structure, causing interference and diffraction that results in the appearance of shifting colors.
One reason is because certain reactions require a precise temperature to occur. If the temperature is not achieved and maintained precisely then the reaction will stop.
When Relative humidity and Atmospheric pressure and a certain temperature combine to make a dew point
Phosphorescence is a type of light emission that can occur without high temperature because it involves electrons transitioning between different energy levels in a material without generating significant heat. This phenomenon is commonly observed in glow-in-the-dark materials or certain chemicals.
Conduction best occurs in materials that are good conductors of heat, such as metals like copper or aluminum. It is most effective when there is direct contact between the materials transferring heat and when the temperature difference across the materials is significant.

If a loss of ductility caused because of temperature, it will be temperature embrittlement. When welding, if cooling rate not controlled, it will leads to faster cooling(Martensitic zone) and will produce brittle structure which normally defined as temperature embritttlement.
