WebJan 14, 2024 · A phase of a thermodynamic system and the states of matter have uniform physical properties. During a phase transition of a given medium certain properties of the medium change, often discontinuously, as a result of some external condition, such as temperature or pressure. For example, a liquid may become gas upon heating to the … WebAug 18, 2024 · Phase changes typically occur when the temperature or pressure of a system is altered. When temperature or pressure increases, molecules interact more with each other. When pressure increases or temperature decreases, it's easier for atoms and molecules to settle into a more rigid structure.
WebApr 12, 2024 · The term change of phase means the same thing as the term change of state. The change of phase always occurs with a change of heat. However the temperature does not change. When we heat a solid, the energy supplied is used to increase the kinetic energy of its molecules, and thereby its temperature increases. WebAug 10, 2024 · The temperature of a sample does not change during a phase change. If heat is added at a constant rate, as in Figure \(\PageIndex{3}\), then the length of the horizontal lines, which represents the time during which the temperature does not change, is directly proportional to the magnitude of the enthalpies associated with the phase …
