In an adiabatic change, no heat is exchanged with the surroundings, so heat remains unchanged. However, the temperature of the system can change due to work done on or by the system.

The temperature at which a solid substance transitions into a liquid state upon heating is called the melting point. This point marks the temperature at which the solid’s internal structure breaks down, allowing its particles to move freely and assume ...
Cryogenic testing is conducted at extremely low temperatures, typically around -196 °C. These temperatures are necessary for handling and testing materials and equipment that are intended for use in cryogenic applications, such as rocket engines, superconductors, and other low-temperature technologies.
Boiling is the process where a substance changes from its liquid state to vapor state throughout the bulk of the liquid, typically occurring at a specific temperature called the boiling point.
The effect on the melting point of a pure substance when another substance is added depends on the nature and quantity of the added substance. Generally, the presence of impurities decreases the melting point of the pure substance.
