There is no one constant coldest thing on Earth, but a copper cube nearly reached coldest temperature possible. Using advanced technology, scientists managed to cool this copper cube to the lowest temperature ever recorded on Earth.
Scientists used something called a cryostat, which was created to keep objects at the lowest temperature possible. Using this, an 880-pound piece of copper was frozen to just above 0 degrees Kelvin. Zero degrees Kelvin is known as absolute zero and is believed to be the coldest temperature that is physically possible to reach. By bringing this copper cube to such low temperatures, scientists not only broke a record but also may be able to do advanced research on subatomic particles that is only possible at near absolute zero.Learn More
Stored energy is most commonly referred to as potential energy, which has the potential to do work. Potential energy is also generally a result of gravity pulling down on an object and can be represented by the gravitational constant of g.Full Answer >
Thermos flasks are designed to hinder heat transfer between the liquid placed within them and the surrounding environment. The insides and outsides of flasks are often silvered to impede heat transfer through radiation. The interior of the flask is also made of a thermal insulator to impede heat conduction.Full Answer >
Most automotive oil coolers pass heated oil through a radiator-type device equipped with a fan that forces air through coils to dissipate heat, explains About.com. Some systems prevent oil overheating by constantly forcing water or liquid coolant through a maze of tubes. Viscosity is drastically reduced in overheated oil, reducing lubricating efficiency and engine performance.Full Answer >
Charles' law states that at a fixed pressure a quantity of gas has a volume directly proportional to its temperature. This means that gas kept at a constant pressure increases or decreases in volume as temperature does the same. As temperature rises, the gas molecules or particles are excited and push at surfaces with more force, creating a greater volume.Full Answer >
