The transformation of a solid substance directly into vapor state without changing into liquid is called sublimation. Sublimation is a phase transition where a solid substance bypasses the liquid phase and converts into vapor upon heating, or vapor converts directly ...

Cryogenic engines are rocket engines that use cryogenic propellants, which are liquefied gases stored at extremely low temperatures. Typically, liquid hydrogen and liquid oxygen are used. These engines offer high efficiency and thrust, making them essential for space exploration. Their ...
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.
The addition of impurities typically decreases the melting point of a substance. This occurs because impurities disrupt the regular arrangement of particles in the crystal lattice, weakening the cohesive forces between them. As a result, less energy is required to ...
With an increase in pressure, the boiling point of a liquid typically increases. This is because higher pressure increases the kinetic energy required for liquid molecules to escape into the vapor phase, thus necessitating a higher temperature to achieve the ...
