Phase transition - Wikipedia
In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas, and in rare cases, plasma.
Phase Changes of Matter (Phase Transitions) - Science Notes and …
2020年10月8日 · A phase change or phase transition is a change between solid, liquid, gaseous, and sometimes plasma states of matter. The states of matter differ in the organization of particles and their energy. The main factors that cause phase changes are changes in temperature and pressure.
11.4: Phase Changes - Chemistry LibreTexts
Summary. Fusion, vaporization, and sublimation are endothermic processes, whereas freezing, condensation, and deposition are exothermic processes. Changes of state are examples of phase changes, or phase transitions. All phase changes are accompanied by changes in the energy of a system.
List of Phase Changes Between States of Matter - ThoughtCo
2024年8月28日 · Phase changes of matter 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.
11.3 Phase Change and Latent Heat - Physics - OpenStax
During a phase change, matter changes from one phase to another, either through the addition of energy by heat and the transition to a more energetic state, or from the removal of energy by heat and the transition to a less energetic state.
Phase change - Energy Education
A phase change is when matter changes to from one state (solid, liquid, gas, plasma) to another. (see figure 1). These changes occur when sufficient energy is supplied to the system (or a sufficient amount is lost), and also occur when the pressure on the system is changed.
14.7: Phase Change and Latent Heat - Physics LibreTexts
Phase changes can have a tremendous stabilizing effect even on temperatures that are not near the melting and boiling points, because evaporation and condensation (conversion of a gas into a liquid state) occur even at temperatures below the boiling point. Take, for example, the fact that air temperatures in humid climates rarely go above \(35. ...
13.5: Phase Changes - Physics LibreTexts
Phase changes among the various phases of matter depend on temperature and pressure. The existence of the three phases with respect to pressure and temperature can be described in a phase diagram. Two phases coexist (i.e., they are in thermal equilibrium) at a set of pressures and temperatures.
1.6: Phase Changes - Physics LibreTexts
Solve calorimetry problems involving phase changes. Phase transitions play an important theoretical and practical role in the study of heat flow. In melting (or “ fusion ”), a solid turns into a liquid; the opposite process is freezing. In evaporation, a liquid turns into a gas; the opposite process is condensation.
Phase Changes | Brilliant Math & Science Wiki
Phase changes are physical changes that take place when matter changes energy states, but chemical bonds are not broken or formed. For example, the physical properties of ice, liquid water, and steam are quite different even though they are all ...
